My husband and I did this while on vacation to visit my mom. We had went to treeumph earlier in the week just to check it out and see if it was something we wanted to do. This is the first plus, there is tons of room/areas for friends and family that don't want to participate to watch and take pictures. We reserved a time for two days later for the first wave in the morning. Which is 8:30 a.m. I highly recommend doing a morning session because it's cooler. When we arrived we were greeted by friendly, helpful staff. The couse is self guided so you have to go through safety training first, but then you are on your own. I liked this because I could do the couse at my pace, I wasn't holding anybody up & vice versa. There is at least one guide at every section of the couseif you need help. It's a 5 level course with each level getting a little bit harder. I would consider myself to be in decent shape and willing to try anything. It was harder than I thought it would be when I was standing on the ground watching 2 earlier. 24 hours later and my muscles, especially my arms are really sore. All the staff was wounderful, they were helpful, friendly and polite. If you want a physical challenge and are looking for something unique to do I highly recommend this. We are already talking about doing this again sometime in the future.
