some things are best left unknown
this hotel is a former HOLIDAY INN franchise that no longer is part of the ICH group and for good reasons. first, the hotel is NOT on THE MAIN riverwalk as its title would have you believe. the city of SA contstruced tributaries of the main riverwalk for future development. the portion of the river walk that this hotel is situated is not developed and is a good ten minute walk to the major atrraction. the hotel is in disrepair. carpeting is dirty, tubs are worn and cant be cleaned, wall paper is peeling and tv are the old 32 inch style with missing knobs, etc. 
there is a dank , moldy smell in the hallways. breakfast buffet is served on hot plates without a sneeze bar.. the hotel is now used by airlines with expiring contracts and large groups looking for cheap accomodations. this is the type of hotel that you would NOT want to use a black light to discover what is dirty and left behind. some things really are best left unknown.
