We are also trying to figure out transportation to Galveston from Hobby. It is the only reason I haven't booked this cruise yet.
We are a family of 5 and need 2 car seats. A rental wont work because we need a minivan or larger but I can't find anything out of Hobby for under $850. Disney doesn't offer transportation from Hobby, and flying from where we are, there are no flights that arrive or depart in a time frame that would allow us to use it anyway from either airport. Which leaves us with shuttles, but I really don't want to lug around two car seats all the way there, on the ship and home again.
