Hotel reservations - San Antonio

I tried to make a reservation at the Drury Inn and Suite near La Cantera Parkway using the Code 3764052.  Online, it would only give me rooms at the Drury Medical Center.  So I called Drury reservations and the same thing happened.  The Drury reservationist was very nice and looked into why that happened even though she had indicated La Cantera.  She says it says TENTATIVE at La Cantera.  Does anyone know why would it be tentative?  I know that the hotel page is not complete (needs links), but this seems to be an issue with the contract with Drury.  Can someone look into it?
