No not at all. But this is no all inclusive vacation whereby you book it and forget it. Research, patience, planning and not trying to do it all, will serve you well.
It's not what it once was:
Only 1 park.
Then add 1 water park.
Add Downtown Disney.
Add 3rd park, then 4th along with a 2nd water park.
Add in fast pass, and 6 month dining reservation and more and more to do on property.
You now get a fairly prescribed vacation, that may not be for everyone.
