I live about 45 minutes-1 hour from South Padre Island. The only two places I can think of offhand are the Radison and the Sheraton. There's a fairly new hotel on the beach side, up by the convention center and its' "whaling wall". I'm not sure but I THINK it's a Holiday Inn Express. We won't be going out to the Island until April 26th, for spring bird migration. Feel free to send me a PM after then.
