Our first trip (3 park days when kids were 4 and 21 months), we only did MK (2 days) and EP (mainly for Breakfast with the Princesses).
2nd trip we only did MK 1 day.
This upcoming trip is our "big" trip - 8 days, 6 park days. We aren't going to MK until the 3rd park day - We have friends coming in for the day on Sunday and want to try to do Jedi training so we are starting with HS. Doing AK the next day, partially to adhere to the "don't go to MK on a Monday" even though it is a slow time of year, and partially to "get AK over with" - The other 4 days will be 2 MK and 2 EP, 1 RD day for each and 1 late night for each.
