it shows in the map it will be between S Rim Dr. and Leon Creek? Not quite sure where thats at.
"The hotels will be located in the NE Quadrant of Interstate 10 and 1604 loop, in the La Cantera
neighborhood of San Antonio, Texas."
wouldn't NE be the Rim and not La Cantera?
my guess is that it is the land immediately to the right as you exit, before the Mimis cafe and Jareds.
