I bought Five-visit climbing punch card of this company from Groupon. I tried some other rock climbing gyms and want to find the best one for my kids. I usually brought three kids and let them play at one time using one card but punched three times. Because the deal is "Five-visit climbing punch card with gear rental included". But this Gym said one card was for one person five times. It's kind of like cheating. They highlighted the deal details:Five-visit climbing punch card with gear rental included but they didn't highlight "one person one card." Other gyms sell their coupons with clear title ......package for one or for two". If it is just five visit card it means just punch five times no mater one person or two persons. I admit I should read all of the deal page. It is a lesson. But I still don't like the way they try to fooling us to sell the tickets.
