I'd love to see a day when "Vacation Kingdom of the World" would again be an apt description for Walt Disney World.
I find I disagree. While there isn't quite a wide variety of things as there once was, and some recent choices or changes are.... questionable... There's very certainly just as many things. There's also still the water parks, and DTD, and the golf courses, and so on.
I mean, sit down and think on it for a moment- what is it people like doing on vacation? Well, different people like different things. Some people like relaxing- WDW offers this. Some people like exploring and learning- WDW also offers this. Some like having a fun, exciting time, which WDW offers.
WDW has Broadway-caliber stage shows (albeit, short ones, but of that caliber all the same), AA attractions, animal exhibitions, a chance to meet people of other cultures and explore their culture (if very shortly- but if you're
that interested in a culture that you want to take more than a few hours per each, you'd visit that country instead anyway), thrill rides, and all forms of areas for relaxation, from pools to spas.
Honestly? I can't think of any other location on Earth that has as much variety to choose from in such a short distance from each other, save maybe the major metropolises- but then, in such places, you run the risk of getting lost.
I think it's still a very apt description, even if you could debate "X place is slightly better than Walt Disney World."
