From what I understand, if you use Disney Air, they will get you to the next port no matter what. That is why I always use Disney Air.
However, after our experience this February, I choose to from now on pay the extra to fly in the day before. They had us on a 6:00am flight, which means checking in at the airport at 4:00. It is an hour drive for us to the airport, so we had to leave the house at 2:30. I was so worried about not getting up, I barely slept the entire night! My entire first day I was a walking zombie.
I am so looking forward to sleeping at the Hyatt, and being all refreshed for my first day! It is only a $50.00 air deviation fee, plus the hotel charges.
