I am looking at a flight that departs from IAH at 1:00pm on debarkation day. Is this pushing things? I'm not sure how long the drive is from the port to the airport? Do you think we need a later flight time? We are using the Disney ground transfers. Also, we are flying in the night prior to the cruise and are including a stay at the airport hotel as part of our cruise reservation. Do they assign boarding groups at the hotel, or will we receive that at the port the next morning? Thanks so much! Any other advice that anyone can offer for this cruise would be appreciated. It will be our first time cruising out of Galveston.
