Cinderellas Royal Table; Breakfast only but dont bother (need to book the MOMENT your day of choice opens and very few seats)
CRT is now also a character experience at lunch (but not dinner). Cinderella appears only in the downstairs lobby; other princesses in the upstairs dining room. You do get to have your photo taken with Cinderella as part of the package. Due to its popularity, it's one of the few dining options which requires pre-payment with credit card at the time you make your ADR (unless you're on the Dining Plan). By all accounts, because of that, it's a little easier to secure than it once was. Having not tried to book it, I don't know how true that is. It's worth remembering that ADRs get cancelled all the time and if you're really keen to get something, it's worth checking back right up until the last minute. The ADR system is specifically designed to allow for "no shows", so you could even get lucky as a walk-up. In fact, the one and only time we ate at CRT was just that.
This is the full list of currently available Character Dining. Eating at the resort restaurants is a great way of getting to see a bit more of WDW.
'Ohana at the Polynesian Resort
Lilo, Stitch and friends (usually Mickey and Pluto)
Cape May Cafe at the Beach Club Resort
Goofy, Chip 'n' Dale and Minnie Mouse (Minnie was only there in a greeting capacity when we did this back in 2000)
- Breakfast buffet
- Clambake buffet in the evening (this one is popular, but I wasn't overly excited about it)
Garden Grove at the WDW Swan Resort
Goofy, Pluto, Chip 'n' Dale
- A la carte breakfast on Saturday and Sunday
- Buffet dinner on Saturday, Sunday, Tuesday, Wednesday and Thursday
Lion King Characters
- Buffet dinner on Monday and Friday
This one flies under the radar a bit. I guess the Swan isn't such a popular choice as the Disney parks and resorts. The dinner buffets have varying themes - The Good Old South on Tuesday and Saturday, A Taste of Italy on Wednesday, American Barbecue on Monday and Thursday, and Fishermans' Wharf on Friday and Sunday.
1900 Park Fare at the Grand Floridian Resort
Mary Poppins, Alice in Wonderland, The Mad Hatter and/or Pooh and Friends

- Dinner served Family Style
Family Style means everything is brought to your table on platters from which everyone helps themselves. As long as you keep asking for more, it'll keep coming. Here, you sit in booths which are arranged around the permitter of a circular restaurant, facing outwards, with the kitchen in the middle. The restaurant revolves very slowly - almost imperceptively - so that your view changes as you eat. At some points, you get to see inside the "Living with the Land" attraction.
