Our current plan is to drive down one day, do four days of Disney parks, take a hotel pool day as we switch hotels, the do one day at Sea World and two days of US/IOA. My kids will be 6.5, almost 4 and almost 1. Does this sound like too much or the right amount? Last time we only did 5 days worth of parks and the kids were 3.5 and 9 months. Five was really all we could handle that time but the eldest child was more challenging at 3 than the current 3 year old.
