My kids would probably have a blast. Would I personally enjoy it? Probably not but I'd suck it up and deal because Claire & James would be having a great time. If one of my good friends were with me, it would probably be a fun day. We could hang out and chat while playing with/supervising our kids.
For little kids, or if I was with little kids...It looks a bit shallow for me to get a kick out of it on my own. I haven't been swimming in about 9 years
