I was doing Disney after my last 2 cruises but this one we were flying out the same day we got off the ship. I opted for a 5:30 pm flight to Seattle. As someone said before kids stay out late that last night, my daughter probably wasn't in bed before 2 am and we had 1st sitting for breakfast so it made for a long day. We decided to hit a movie at DTD and my daughter slept through most of it. She was also sleeping in the airport as we waited to get on our flight. She was fine after that until we got to our flight in Denver and sat on the plane for 4 hours before finally arriving at Seatac at 2:30 am around 4 hours late. If your kids take full advantage of the ship they probably will struggle in the parks but you really need to figure it out yourselves.
