Refer to the attached link which can be extremely useful as to hotels, bidding strategies and results of previous bidders. As always, you are bidding on a star quality in a zone and not any particular hotel. Good luck.
We stayed at the Commodore Jan 15th. They will let you leave your car, while on cruise and also free shuttle to and from the port back to hotel. Very satisfied with their services. Will use them again next cruise out of Galveston. You can find them on the web. Their charge was around $50. a night. I only stayed one night.
