I find myself drawn to the character meals. It will be myself, DH, DS 11, DD 8, and DS 4 - we are on the DDP. Am I doing too many buffets/character meals? Also, can the kids on the DDP eat anything off the buffet or do they have to stick to just the kid selections? Please review my ADR's and tell me if it is ok or if I am missing some great places to eat. We do not want to do any 2 TS places nor CRT.
10/22 Epcot day - Garden Grill for dinner

10/24 MK day -CP lunch and CM dinner

10/26 DHS day -Fantasmic dinner pkg - H & V
10/27 unplanned day - Coral Reef dinner
Epcot Day: I would skip Garden Grill and eat in World Showcase somewhere... we made ADR's for Biergarten and never made it so we are aiming to make it there next time, but we have eaten at 9 Dragons (China) and San Angel Inn (Mexico) on multiple occasions and always enjoyed our meals. I guess it depends on what you and your kids like to eat

If you're set on a character meal, try Akershus in Norway. It's a princess meal so your boys might not be too keen on it, but your daughter will talk about it long after the trip is over! Or you could change your ressie all together and have breakfast with Lilo, Stitch, Mickey, and Pluto at Ohana (at the Poly). Epcot is a short monorail ride away!
AK Day: Tusker House is good but we prefer to go to either Yak & Yeti or Rainforest Cafe. Although on AK days, we have also been known to eat a CS lunch (like Pizzafari) then leave AK at closing and head to DTD or another resort for a TS dinner. In our experience, the Rainforest Cafe at AK is MUCH better than the one in DTD. I don't know why, but the food has been fresher and the servers much more attentive.
MK day: I've never been to Chef Mickey's personally so I cant say one way or another whether this is a good choice or not...A lot of people love it, a lot of people say it's just so-so. If you decided not to go on your Epcot day... I would go to Ohana for breakfast then move my Crystal Palace ressie to dinner and pick up lunch at Casey's or something. The Plaza Restaurant in MK is also VERY good.
DHS day: The Fantasmic Package is hit or miss. You pay the reservation charge and if the show is cancelled due to inclement weather, you don't get your money back. And the seats that they "reserve" for you are all the way to the left of the theater when you walk in, so you're not even center stage. I've also heard a lot of folks complain that the food at Hollywood & Vine is cold (due to it being a buffet and just sitting out for a while) or just lacking in choices or taste. I would skip it and go to Sci Fi or Mama Melrose's. We've had great meals at both!
Coral Reef: Great choice! The restaurant is beautiful and the food was dee-lish!
