Our early morning riverwalk cruise was informative and pleasant, with very few of us on the cruise at that early hour. The hop on/hop off tour was most awesome for the variety of sights to see and the reliable transportation to some of San Antonio's best shopping experiences over 2 days.
The hop on hop off bus trip was good - not a lot of things to hop off for but a nice way to see the city. The river walk cruise was very busy and the sound system on the boat was not up to par at all. We went at dusk and the river walk was very crowded.
