How does the pool work? Like, do we keep our clothes in the locker and then come back for them when we're ready to shower or what? Also, do we take towels to the pool area or no?

The pool operates on first come basis. There are lockers available for your use or you can take your clothes with you to the pool area, whichever one you feel comfortable doing. Yes you can take your towel to the pool area

They also have a shower in the pool area for you to rinse off. I bring a lock too for the lockers in the locker room.
