With 125,000 rooms for rent, including those in the world's 10 largest hotels, Las Vegas should have more than enough room for you and your brood. Or so it seems. But when a convention, a fight, or other major event happens--and they do, almost weekly--all of a sudden, the rooms evaporate into the desert air, or at least skyrocket in price. However, with advance planning, you should be able to choose your vacation in a Vegas version of Paris, Venice, New York, Ancient Rome, King Arthur's England, Egypt of the Pharaohs, or simply a pleasant hotel with a gorgeous pool.

Hotel rooms in Vegas are low-priced compared to similar rooms in other vacation locations, but there are some drawbacks. Most hotels are casino/resorts, which means huge premises with long walks, through often-smoky casinos, to get to and from your room to anywhere else on the grounds. Minors cannot be unaccompanied at any time in casino areas, meaning that you'll have to walk with them whenever they want to go to the pool, the arcade, or the animal attractions.

Non-gaming properties (yes, some places in Vegas actually do not have casinos) are located off the main drag, requiring a bit of planning and a car or cab in order for you and your kids to make it over to the Strip so that you can gape at all the wonderment it offers, such as volcanoes and talking statues. While these non-gaming resident and apartment-style hotels, where each room comes with a fully-equipped in-room kitchen, make it easy to cut meal costs by preparing food en suite, again, you will need a car to get to the market or convenience stores in order to take advantage of the pots, pans, and plates these hostelries provide.

Las Vegas's new identity as a resort location has yet to settle in completely. The pools at the self-proclaimed luxury resorts are often chilly, close early in the evening, and at some properties, may partially shut down during the non-summer months. Plus, some kids can quickly get bored with the whole pool experience, in which case, staying in a place with cool stuff to do, or at least an arcade and a lot of television stations to keep them preoccupied, is a really good idea. Keep in mind that though these properties bill themselves as getaway locations with astounding shopping opportunities, we couldn't find a real bookstore in any of the hotel malls, so if your child likes to devour books on vacation, you should plan ahead and bring a supply or be prepared to drive to the nearest bookshop. The same situation applies to CD stores, so it's a good idea to load up on music in advance.

The most important factors, after your family's needs and interests, naturally, are location and price, because at a certain point, most hotel rooms are surprisingly similar. Granted, some rooms are larger than others and some have nicer furnishings, but basically, your room is only a place to rest between sightseeing adventures.

Most of the time in Las Vegas, the difference between paying $69 for a room and $250 for the same bed/bathroom/TV combo is the date you plan to stay, because Las Vegas has incredibly fluid room prices. Be aware that there is no standard for what is considered a "child." Some hotels charge an extra person fee for anyone over 7; others feel the cut-off age is 17, and some grinches will charge no matter how old or young the extra person. At certain properties, the extra person fees are seasonal or changeable, based on "specials." Don't be afraid to ask.

One thing you'll notice is that while, in many cities, hotel chains have the corner on ultra-luxurious, or at least large, substantial properties, in Las Vegas, with its abundance of over-the-top, super-sized resorts, the usual, standard-name hotels recede into the background. Sure, they are still nice (especially if you are on one of their frequent-visitor programs and get points for laying your head on the pillow), but they do pale by comparison to the pyramids and palaces that are almost mini-cities unto themselves.

The one thing that is fixed about room prices is the tax; as of press time, you will pay an additional 9% tariff in Clark County and 10% in nearby Henderson for hotel room taxes.

You should know that price might not have anything to do with the quality of the hotel's other clientele. Even the nicest hotels can have rowdy--well, let's be blunt, drunken--guests, especially if there's a holiday, convention, or big sporting event in town, or even if it's a Friday or Saturday night. And because the rooms are mass-produced--no matter how nice the hotel--you will hear plumbing noises, conversations (and sometimes more) from next door, along with the pitter-patter of little feet in the room above you.

Many of the classic Las Vegas hotels have fallen to the wrecking ball and demolition experts, or have been renovated so they no longer resemble their old images. In their places are the new kids on the block, bigger, but not necessarily better.

Everyone thought entrepreneur Steve Wynn was nuts when he envisioned, then built, the huge Mirage, with its jungle foliage and erupting volcano. But the naysayers were mistaken; the Mirage was a success, and the race to build successively more stupendous resorts was on. Circus Circus, Excalibur, the MGM Grand, and Treasure Island began courting families, until the bottom-line men realized that Las Vegas was never going to be the next Orlando. Wynn, in a firm anti-kid move, built the Bellagio, which, while its gift shop has some cool stuff for kids, isn't otherwise exactly the most kid-friendly place to stay. The MGM Grand, which also owns New York-New York, banished their kiddie-oriented ethos and took over Wynn's Mirage group (Bellagio, Treasure Island, and the Mirage). Suddenly, the latter two of these hotels revised their welcome with regards to families, while, according to numerous visitors, service and attention to detail dropped noticeably.

Meanwhile, Downtown, which had gotten progressively shabbier, underwent a major revitalization, thanks in great part to the Fremont Street Experience, a multimillion dollar light-and-laser show that draws crowds nightly to what is now a pedestrian promenade lined with cafes and shops. It's a nice place to visit; but we still don't suggest you stay there with your family.

Both the Stratosphere Hotel and Sam's Town Hotel & Gambling Hall have undergone major re-dos. In the case of the former, most people feel the current semi-theme of upscale amusement park coupled with a decent, low-cost hotel works as well as anything could, given the hotel's location at the very furthest end of the Strip. But many regular visitors bemoan the changes at Sam's Town, including the loss of its diner with tasty, traditional food.

Steve Wynn has now gone off on his own, to build anew. His latest project, a hotel called Le Reve--named after one of the Picassos in his collection--will stand on the location of the old Desert Inn; currently that spot houses the Wynn Collection, featuring 13 paintings by modern masters, including the resort-to-be's namesake.

Allegedly there's to be a London-themed hotel/casino to be built on the North Strip, and a San Francisco-based resort going in as well. Only time will tell--and quickly at that--the fates of the Aladdin (newly updated, but facing bankruptcy); the Tropicana (reported to be teetering on the brink of closure, or at least a major renovation); the Hilton (supposedly on the auction block); and any other hotel that doesn't meet the expectation of the corporate owners.

The majority of visitors with families stay on the Strip, because that's where most of the attractions can be found. Downtown is not a suitable location for families, trust us on that one. Both to the east and west of the Strip are decent to fine hotels, but you'll need transportation to get you there and back. And while staying on the Strip provides you with heaps to do and see, keep in mind that the hotels are farther apart than they appear, especially while walking in 100°F (38°C) weather or on a cold, windy night, with children in tow.

Price guidelines are rough, given the flexible nature of Vegas's room rates. But that doesn't mean that you shouldn't call the hotels directly to see what kind of rates you can get. Given the state of the travel industry since the terrorist attacks of September 11, 2001, as well as the continual stock market fluctuations, you might be able to land a truly great deal. Expect to pay a bit less than rack rates Sunday through Thursday, and a bit more on Friday and Saturday nights.

(tel. 877/632-5000 or 702/632-5000;, is a very expensive hotel, unlike other casinos/resorts in the area, the use of their ultra modern, state-of-the-art health club is free.
