Rented a car and stayed in a hotel near the port the night prior. Parked at the port for the duration of our cruise. Drove back to the airport after we disembarked. It was cheaper to rent a car for a week +1 for our family of four than it was to hire a shuttle. Our original plan was to keep our car at the hotel and take the shuttle to the port, but they filled up their schedule!! They failed to tell me we needed to out our name on a list and by the time we inquired, they were full! It all worked out ok. But, kind of a shame to rent a car and only drive it for about two hours!! This was before Uber and Lyft, they may be options now for transport from and to Hobby.
