Speaking of the pool, is there a good time to use it to actually swim for exercise? I noticed they have lanes, do they ever block them off for swimming? I tried to swim one evening, but 3 kids pretty much dominated the whole pool, and I didn't really feel entitled enough to ask them to stay on one side. I don't have any kids so I don't really get any other use out of it. Just wondering if there is a time slot for adults to use the pool.
