Disney World is a lot of fun, every few years we go there over Christmas. Wonderful time of the year to be there. The night shows are fantastic. It is super commercialized and you expect it. In terms of cost, well? It is what it is. Reframe the conversation and say, no amount of money could explain how much fun the kids and I had.
Disney is A-OK, but my favorite is Epcot. In the 1980's, when I was in the geodesic dome, on an "Alien" ride for the movie...it scared the ... made an impression let's say, that never left. I like Disney for the Brand equity and strength the brand has, but my favorite has to be Epcot.
