I went to Treeumph with my husband and my children (11 and 8). We all had a blast! My son wasn't big enough for the adult course, so he was able to do the child course 3 times. My daughter, 11, was able to do the first 3 adult courses with us. My son did one turn on the child course while we watched. Then, the 3 of us did an adult course while he watched. We kept taking turns until we all did 3 rounds. The adult courses got progressively harder. It was my husband and mine's first time, so we were fine just doing the first 3 adult courses with my daughter. Maybe next time we'll complete the 4th and 5th courses (if we're in better shape by then!).
We all had a blast and would do it again!!
