We chose to stay in San Antonio for the recent F1 Grand Prix weekend, and couldn't have been happier with our choice of the Hyatt Regency. We had a wonderful spacious corner room overlooking the riverwalk - the only negative thing I could say about the hotel was that for such a large room, the bathroom was tiny. Some additional space could have been used to expand the bathroom to allow more than one person in at once. Otherwise a perfect place - the staff were all extremely helpful, right from the valet parking guy who met us the moment we pulled up, to the maids and wait staff in the restaurants and bars. All were interested in why you were there, where you came from, when you would be back - that personal touch makes a big difference.
And you couldn't have asked for a better location - right over the road from the Alamo on one side, and backed right up against the riverwalk on the other.
We will definitely be back to visit again - I think the Hyatt Regency will now be our regular place to stay when we are at the F1 GP !!
