DON'T USE THIS SERVICE. We waited 1 1/2 hours for their shuttle from Houston Bush airport to Galveston Cruise Terminal and they never showed-up, although they kept telling us on the phone they were on their way.
Our plane was delayed and we were in contact with them about the delay. Also contacted them when we landed! We were told to get our luggage and wait for them to call and let us know which door to meet them at. We waited for their call, but finally contacted them and were told they were on their way.
Called again after 30 minutes, they said they were on their way. Called again after 30 minutes, and told again they were on their way.
Finally after waiting 1 1/2 hours we took an airport taxi. The regular airport taxi are cheaper.
