Head through the womens shower/locker room

You are in the womens section, even though clearly you are not a woman. Naughty! You're not allowed in here! The locker room is clean-ish, with just a few stains here and there, and some scattered swimming equipment lying about. There's rows upon rows of bright green lockers, most of them locked, though a few of them are left open, and you spot things inside. You can't imagine what "loot" you could possibly find in a girls locker room that could prove remotely useful to your current situation, but you could take a look.

You can also hear banging coming from inside the closed off toilet, a bench leaning against it, barricading it from being opened. You think you might have an idea as to what is in there.

You could also head onwards to the pool through the showers.
