We did the tour and were very glad we did. There are several options to pick from. We only did the half hour tour and it was perfect. Our tour guide knew quite a few of the "urban legends", but not very many of them seemed very believable.
The River Walk offers so many different things to do. We ate dinner, dessert or had drinks somewhere along the river every day we were there (5 days).
Definitely something fun to check out while in SAT.
