We did 8 nights/9 days with a 6 year old and a 10 year old. Here's what we did: lots of 1/2 days at the park, with 2 days when we didn't go at all. I think we paced it about right.
Day 1 -- arrived around 3 -- afternoon at MGM/Fantasmic Dinner Package
Day 2 -- M.K. opening (EMH a.m.) until about 1:30, then tea at the GF, then back to the hotel until Dinner at CG
Day 3 -- slept in, a.m. at the pool, 10 y.o. and her mom went to PS Lunch and did WS, 6 y.o. and his mom (that's me!) stayed at the pool longer, did Beaches and Cream, and then joined the others for an hour or so of WS and dinner at Marrakesh.
Day 4 -- Epcot a.m., switched resorts in p.m. (BC to SSR), grocery shopping and then Chef Mickey's.
Day 5 -- Slept in a little, then drove to Cocoa Beach for the day, came back and went to DTD and shopped/ate at Fulton's.
Day 6 -- M.K. for opening until Lunch, then back to SSR. Friend and her daughter went to the spa for mani/pedi's. DS and I stayed in and watched a movie. Cooked in the villa and had a quiet evening.
Day 7 -- supposed to be BB but DS woke up and begged to go to the beach again (Please mommy, I don't want to stand in line today). Changed to AKL in the evening, and ate at Jiko's.
Day 8 -- slept in A.K. most of the day, dinner at Boma's
Day 9 -- checked out really early, morning at M.K. lunch at Crystal Palace and then flew home.
