I just registered for the princess half marathon, and since we have never stayed at an Epcot resort, I thought it would be fun to try this time. We will probably be having dinner in Epcot most nights, and I think my kids will enjoy DHS. Which of these 3 would you recommend with 3 boys, ages 8, 6 and 2? I have always wanted to stay at BC/YC for the pools, but it will be February and the weather could be iffy (though it probably won't matter to my kids!) a friend recommended BWI, but i don't know much about it. Swan or dolphin are also possibilities. Thoughts?
