She smiles at you, "Oh, that's okay. Mistakes happen." She was about to enter the door when you asked your question. "Oh yes, there's an intercom in the room that'll let you contact the front desk. You can tell my brother what you need, and he'll set you up with what you need, enjoy!" With that, she enters the room leaving you to enter one of the other available private rooms.
Entering the room, you found yourself in a small room with a place for you to leave your personal belongings and a pile of fresh towels. From the next room, you could hear the sound reminiscent of a babbling brook. Looking into the room, you could see the pool. In the middle was a pile of rocks from which water was falling down producing the sound you heard. By the side, you could see a small console which must be where the intercom can be found.
