I think it is pretty simple:
Neighborhood pool - 30 yo or older
Sport pool - 30 yo or older AND resident AND lane restrictions at times due to activities that are posted.
family pools - any age
It says noodles are allowed. Don't see where floats are.
If anyone sees language that is different from above please cut and paste it in your reply since the pages you are linking to clearly don't. (and make sure it is current).
We were told 'no full size floats' in the pool and we abide by that when we visit. Before you know it you'd have full size 'fun islands floats' out there
