San Antonio, Texas
It wasn't Grand.. Viator promises things that are not even covered on the tour.. the Governer's Palace for example. It's a good tour if you have limited time and no car. The guide was knowledgable and entertaining, though gets points off for the "Preaching Catholicism" at the mission.
Not great, it was a overcast day so we could see the views of the hills and I had envisioned a little more than a quick drive by. The guide was okay but there were only 6 of us and he didn't even bother to ask where we were from or have us introduce ourselves. I would not recommend this tour - you are better off doing a walking or biking tour (skipping hill county -especially on a cloudy day).
