Crowd levels are too high.
Although word is this may be changing.
I don't mind expensive, so long as the experience is commensurate with the price. Too many cuts for that to be possible.
I will say the planning requirements are a bit ridiculous, but I figure they are related to the overbooking/crowd levels.
I think of WDW like I do the newest cruise ships. They can handle way more passengers, but the venues remain the same size. If I go cruise/WDW I expect to be able to see and do everything I want to do. Anything sold out seems like a gee-golly scam to me. Don't sell the ticket if you cannot deliver the goods.
