One of the benefits of age is that travel to most destinations often costs less -- but that's rarely true in Las Vegas. Discounts at hotels, shows, restaurants, recreation, and just about anything else you want to do are rare. About the only discounts offered to seniors are at some of the local attractions, which will give a few bucks off to those over 62 or 65.

The U.S. National Park Service (NPS) offers an America the Beautiful -- National Park and Federal Recreational Lands Pass -- Senior Pass (formerly the Golden Age Passport). You'll find it useful for some of the side trips. The pass gives seniors 62 years or older lifetime entrance to all properties administered by the National Park Service -- national parks, monuments, historic sites, recreation areas, and national wildlife refuges -- for a one-time processing fee of $10. The pass must be purchased in person at any NPS facility that charges an entrance fee. Besides free entry, the America the Beautiful Senior Pass also offers a 50% discount on some federal-use fees charged for such facilities as camping, swimming, parking, boat launching, and tours. For more information, go to www.nps.gov/fees_passes.htm or call the United States Geological Survey (USGS), which issues the passes, at tel. 888/275-8747.
