Undercover Tourist (www.undercovertourist.com) passes along only a small discount from what the theme parks themselves charge (like $15 off the $285 price for a six-day "Park Hopper"); you buy your various multi-day passes to Walt Disney World, SeaWorld, Islands of Adventure, Universal, etc., for just a few dollars less than you'd pay in Orlando.

But this easily understood website is more helpful in displaying the choices you have. It lists what is available in clear-cut fashion, and dispenses with the need to stand in line at an admissions kiosk upon arriving in Orlando. It also prices its products in "all-in" fashion, adding taxes and other fees to reach an all-inclusive figure. And then it ships the passes to you without charge.

The problem, of course, with any Orlando passes is that they tend to confine you to one particular group of theme parks, like Disney's or Universal's. They give you a powerful incentive to do that. But once you understand this condition of their pricing, you thereafter enjoy a considerable saving off the price of purchasing individual, single-day admission tickets.

I think you'll enjoy surveying Undercover Tourist's products, and thus learning what the ultimate cost will be of that Orlando vacation.
