This is amazing, and our kids love it. When my 3 sons have their friends over,(Maybe 9-10 kids total) we set it up as 3 different courses so everyone has fun and when it's just them or a few friends we have is as 1 big obsticle course. They all love it and hate when its winter and they can't use it! Expensive but when they use it almost everyday when its hot or summertime, i figure its worth it. They also love it when its semi hot when water doesn't dry fast,(Maybe a hot summer night)and they literally DRENCH it with water and they slip and slide everywhere and takes them forever to go through it! It is GREAT and loads of fun!
