This was a terrible experience!
The staff was very rude and unprofessional. We went there on a Groupon and I have to say that they clearly don't like to honor them. We called to book our time and we were told that they are booked for the sunset rides (which is what we purchased) but they can put us on a day time ride and give us back a $4 difference per person (which seemed fair). We agreed to that, but when we got there they said we have to pay more because we got a special price on Groupon. So, we were going to have to pay $11 more per person, no chili bowls and get a ride which was not our first choice. The problem is that we were not the only ones...another group was in the same exact situation as us, so it seems that it's normal practice for them. Why not be an honest business and get off Groupon if it doesn't work for you?
We also heard them referring to a gentleman around us as "the big guy"...not cool!
