if you are staying onsite and choose to utilize this option. Regardless, with the exception of our first trip, we always choose to go to MK first. This park usually takes more than one day to complete, so we do 2 (or 3) partial days there. You can always hop over to Epcot or MGM later in the day. If you do AK, I wou;d go early, then take a break, then go on over to any other park for the rest of the day. Also check the parade schedules on Disney's own website to see which evenings and what times the parades/nighttime shows are in each park, to better plan your schedule. If you have PS reservations at any of the park/resort restaraunts, you may wish to base your park schedules around those. If there is rain any of the days you are there, you might want to do Epcot, because there are a bunch of indoor attractions there. Have a ball!
