I had the opportunity of having a "VIP" tour, since I was the only customer on that Monday morning for the standard tour. The guide was very professional, gave me a lot of explainations about the different phases of the battle and also about the growth of the city.
The walk itself was not so long, with plenty of place to sit if you're not as fit as you could.
I would definitely recommend this walking tour.

My sister and I recently took the History walk and really enjoyed it. Gary spins a great tale of the history of the city, especially the battles around the Battle for the Alamo. He re-creates the scene very vividly and you are transported to the past. He then walks you around the downtown area explaining the history of Texas, San Antonio, the river and virtually everything you would like to know about the beginnings of Texas. The walk is easy, and through most of it you are seated. He does ask you to wait until he finishes at each stop to ask questions. Well worth the money and far superior to those on-off bus tours where you spend half the time waiting for people to get on and off, This is individual attention

it's the only place where you find river below the streets and the busy area... it's a must for all types... couples/family/friends and solo... don't forget to visit the tower as well ...
