One thing to remember, too, is that you can still walk up to any of the character meals and get a table, even without a reservation! You may have to wait a while, depending on how busy the restaurant is, but reservations are not required. I've enjoyed many meals at Goofy's Kitchen and the Critter Breakfast (and more recently, at Surf's Up) without reservations.
The reservations are not real reservations in that there are no tables held for your party, as there would be at regular restaurants. The reservations are simply a way of giving you priority in getting seated over other people who didn't make reservations.
And even then, depending on what the size of the table is that needs to be filled and how many chairs there are, the restaurants may still seat people who do not have reservations before the people who do have them. For example, you may dine at Goofy's and you may have a reservation for 5 people. If 2 separate tables open up that seat 2 or 3 people each, chances are that the host or hostess will look for parties of 2 or 3 waiting in line to fill those tables even if those folks do not have reservations. So those folks could be seated before you.
Anyway, I just wanted to point that out, because sometimes it's nice to have the flexibility of being able to decide on a whim, "Let's eat at Minnie & Friends this morning!"
