Go to one of the pools

After the long journey, refreshing a bit would be nice, so you decide to go and look for one of the pools.
You grab your swimwear and a towel, so does Emily, and you head out.
The big window by the staircase shows you that the sun is about to set, and the sign by the elevator tells you that one pool is up on the roof.
The elevator takes you to the floor right under the roof, where the showers and changing rooms are located. From each changing room is a staircase up to the roof, men and women seperated, but they lead to the same place.

You agree to meet Emily on the roof, then you enter the changing rooms, which are right next to each other.
You close the door and look around. You are alone.
There are some benches, and some lockers, as well as an open shower area.

You strip out of your clothes and put them in one of the lockers, then you put on your swimming trunks.

You are just about to leave as you notice a gap in the wall by the lockers, right by a black wall with some secial offers and pool rules put up.
While you step closer, you realize that this is the wall between the mens and womens changing rooms.

You lean down a bit, and look through the hole, and indeed-it shows you the womens changing room.
