Let's start with a few:
The continual ticket price increases with little or no notice (I get the fact that prices will increase - It's the "no notice" way they go about it that irks me - give people some time to plan, adjust, or absorb.)
The percentage increases on many things (ex. food and beverage). - Again, I understand things increase. But they don't increase year over year to the extent Disney increases them.
Cost cutting in lieu of quality (This spans across food and beverage along with merchandise). This is one of the major ones for me.
Selling a park 3 times in a day thus devaluing the ticket of the individual who gets booted from the park early unless they fork over more cash for the hard ticket.
These are really fair complaints. I think for the first one though, unless you're renewing or purchasing on the day that it changes one could argue that you have some sort of notice. #2-3 are why I spend a lot less in the parks these days.
