In San Antonio for Fiesta Texas, the $44.95 price is per person IF you purchase a 4-person family pack. Otherwise the price is at last check was I think $69.95 if you only want one pass. If you work for DOD on a govt installation, you can get discount tickets and passes at MWR. As far as the water park - in San Antonio it is part of the park and there is no additional charge for that.
