Great restaurants, beautiful scenery, fun bars, lots of hotels, tons of tourists, several locals hangouts, barge rides........the San Antonio Riverwalk is pretty much a "can't miss" daytime activity...and if it rains, just go get some mexican food at Casa Rio or some italian food at Paesano's, or some BBQ at The County Line, and then head over to Dick's Last Resort for some day drinking. Howl at the Moon is always fun stop too!
