...happened to me a few times, even earlier for me at 1am arrival. Leave your bags at the hotel and go out until the bars close. I guess you won't be able to check in til 11? or so, if you are in San Antonio, there was a bar/pub called "sun and moon" which is now the "Willow tree". The "sun and moon" used to open at 6am and served english breakfasts, but don't know if it's carried on with the new owners sorry... Anyways, first year it happened to me I didn't know what to do so just stayed on the beach til 10am...
