The Dolphin offers 2 hours of complimentary kid care at Camp Dolphin if you are going to eat at the upscale restaurants (bluezoo, Shulas, Il Mulino). These 3 are pretty adult oriented.
The great thing about staying at an Epcot area resort is that you can easily walk to Epcot with there's a large number of dining choices. At the resort area, there is Cape May at Beach Club, Yachtsman Steakhouse (more family friendly than Shulas) and Captains Grille at Yacht Club, Kouzzina and Flying Fish at the Boardwalk. There's also the Big River Grille, Beaches and Cream and ESPN plus the casual places at the Swan/Dolphin.
I've made reservations at Swan/Dolphin at 180 days out before and I've also made them the day of.
