lOTS OF GOOD TIPS.
If you have little ones:
Be sure to bring your own strollers. Not only a time saver but easier to find in a crowd of strollers...AND you get to have them while waiting for buses (or bringing kids to the parking lots) and around the hotel.
Going back to the room for a rest is not always the best plan. when ds was 2.5 we could return to the room and all 3 of us would nap. Biggest problem was sometimes we woke too late for our dinner PS! But that was ok, we'd opt to eat in hotel food court and get to the parks around 6, well rested for a late evening. When dd was 2.5 (and ds5.5) room naps were more frustrations that resting! By day 3 we just stayed in the parks and let dd nap in her stroller. We did a few rides swapping off w/ ds...and used the time to shop, sit and rest, etc. DS was able to go a whole day, and at night time, he was tired, so he'd go right to sleep..and w/out him awake...dd would go to sleep. ahhhhhhhh
