This is a fun activity; a great way to your the area around the Riverwalk! And it's so easy once you get the hang of it Matt was a terrific guide once we got started. He really made sure we knew how to ride safely and he knows the area very well.
I took off a star because for two reasons.
1.) There was absolutely no one there when we arrived at the Historical center and very little instructive signage to let us know we were in the right place. Evidently Matt's earlier tour ran over which is no big deal but it would have been nice to know.
2.) There was too much pressure on tipping! Okay, I get it, tipping is appreciated. But I personally found the constant reminders off-putting.
All in all, it's a great experience to add to your vacation.
