If you buy your tickets through AAA, you can also purchase vouchers for the character meals. I was given the impression that we could order just the vouchers, but I added hoppers so I'm not sure about that. The vouchers are a very good deal and include tax and gratuity. Here are the current offerings and prices:
*Goofy's Kitchen (Brunch and Dinner)
*Lilo & Stitch Aloha Breakfast
*Chip 'n Dale's Critter Breakfast
*Minnie & Friends breakfast
*Ariel's Grotto (Lunch & Dinner)
Breakfast $25.60/adult $14.45/child
Lunch/Dinner at Ariel's Grotto $25.60/adult $17.80/child
I am not really sure what the price is for dinner at Goofy's. The above doesn't make it clear, but that is the price list I was given from AAA. I bought our vouchers over the phone from my local agent (actually, I paid a deposit and will pay them off in a month), but you can also order them over the phone from the central office, or at least you can where I live.
As far as the park hoppers, you can include everything as a package (tickets and vouchers) and then you just put down a deposit. I think you have to pay it off 30 days ahead of your trip or something like that. Our local office doesn't carry anything more than the 2- or 3-day hoppers but they will order them for you. The prices are the same, I think, as the advance purchase through disneyland.com but there are a few perks (free parking, Diamond card, etc).
When I compared prices, AAA vouchers were the best deal on character meal vouchers, but GAT was close and so was the Orange County visitor's site
