Yes, I would strongly recommend calling ahead and making a reservation. Check out their website goziptexas.com
You will love it! The training before was very in depth. The guides were very flexible and knowledgeable. There were two of us and I believe it was about 100 for all of the lines per person...and it was very worth it. We paid at first for the first section then added on in the end and paid the difference when we returned.
Yes, call and arrange reservations.
