We have been to Goofy's kitchen and it was well worth the price. the buffet was decent with a good selection of NON breakfast items as well as breakfast itesm. THey have made to order eggs/omlets, waffles shaped like mickey, sausage/bacon, potatoes, bread, begals, fresh fruit, and yogurt. I believe they also had various salads and veggies (marinated tomatoes I know for sure). There was also a Peanut Butter and Jelly pizza that was great. The desert area was stocked with cakes, muffins, danish, tarts, cookies and such. I think there might have been some lunch meat and rolls. The price is the same for breakfast/brunch, but it increases a bit for Dinner. I think the hours are breakfast/brunch until 1pm, so you could always go closer to lunch time then head to the hotel for naps and a swim.
The character interaction (in my opinion) is worth the price alone. We had great one on one time with Snow White. There was no line and my girls were able to see her 4 times and each time she spent at least 5 minutes with them. She stood near the dessert area but all the other character came to our table. We saw Pluto, Goofy, Baloo, Mad Hatter, Donald and Gepetthio.
We were sat near the Character exit/entrance so every time the Characters left for a break the girls would get a high five or a lick from Pluto (the hilight of the trip for my 18 month old)
We have also eaten at Ariels Groto in DCA. It's a fixed price meal (lunch or dinner) and you have less choice of food, but the character interaction was also good. Ariel sits near the front, but the other character roam around the table. We saw Ariel, Minnie, Goofy, and Pluto here.
I would pick Goofy's kitchen first, then Plaza Inn for the Pooh Characters. If you decide to go to Goofy's or Storytellers make priorty seating reservations, I think you can make them 60 days in advance.
