We have used Galveston Express in the past, and found them to be a great service, however for our summer trip with a larger group of people we have gotten a better price from a company called Galveston Shuttle and Limo. I'm wondering if anyone has any experience with this other company to give us some guidance on whether or not to go with the lower-priced option or stick with a company but we have used before.  Thanks in advance!
