We just got back from our first trip (week long) on Saturday. DH, DD 3.75 and I for the first 3 days, DH returned to his office, my Dad and his wife and my DD for the remaining 4 days. We got the park when it opened (MK on Saturday and Tuesday) and managed to ride everything in Fantasyland and BTMRR and Splash all before 11:30 both days. My daughter grew addicted to BTMRR and Splash and thereafter didn't really want to ride anything else, so we did alot of fast passing and standing in line and would leave the park around 2:30. We would go back to our off-site resort, swim, have an early dinner, and then a couple of nights, returned to Epcot. The touring plan for Girls 4-8 worked really well for us, even when we had a 9:10 CRT on Saturday.
Overall, I think we had a great Disney experience, and I don't think it would have been as nice had we not followed one of the touring plans from the UG and left the parks in the early morning.
