Do you have a jumping castle / inflateable water slide? Are they worth it? Have you had a puncture? Are they easy to set up? Would I be able to set it up and put it away myself? Anything else I should know? I am thinking about maybe getting one for my kids for christmas (age 5,3, 17 months and a newborn when he gets older).I looking at one like a happy hop one. So worth it or waste of money?
