Two points out the blow up pools. Not to flame, just to raise a couple of points to think about....
After they're used on deck, where would one dump out the water? I'm thinking a CM would probably stop someone trying to pour it back into the pool area, since that would defeat the purpose of keeping non-potty trained kids out of the pool. Is there somewhere else around there it could be dumped out?
And secondly - if you go with this idea, and the CMs are enforcing the rule that day for some reason, you may end up being approached by several parents asking if their little angel can play in your pool with your child too. Again - then that puts your child in the pool with another non-potty trained child... uck (if there's an accident).
