I was always a bit put off at the idea of buying a bouncy castle, however I recently found out that you can buy some that are small enough to fit in the average back yard when inflated, yet still large enough for several kids to play on. I found this site: inflatable bouncers reviews, and went through them different reviews listed there before purchasing the top rated bouncer, which was a blast zone one. It had the best reviews on Amazon, and people who had previously bought it seemed very happy with their decision.
Upon delivery, the inflatable bouncer was quite compact when not inflated, so could easily be stored somewhere when not in use. I just hope that we continue to have a good summer so that we get maximum use out of it, I would not want to use it during high winds or bad weather.
