Yes, this. We just got back from a 9 day visit with our three year old. We had a lunch ADR on a day we were very tired. After 4 days of sheer exhaustion (i.e fits) our daughter FINALLY took a nap at the hotel. We felt forced to wake her up to make the reservation because we didn't want to be charged $30 for not showing up. Needless to say, it was not a pleasant meal.
For a place geared toward children and families there is very little flexibility.
My husband decided half way through the trip we would not be returning as a family for next years vacation (we went last year as well, and DD and I went twice this year with my parents). DH has a very stressful, fast paced, over scheduled job and he said a week at Disney was just as much anxiety as work.

Too much planning/scheduling/stress for vacation.
(Not to mention it was $70 for us to eat breakfast at our hotel. DD was charged $14.99 for eating a bowl of fruit loops...and she didn't even use milk!
