You begin looking into a shower. Go ahead and turn completely around because that's just weird and realize that this is some kind of massage room. Escape the massage room. You should see some arcane glyphs in the floor outside. Skirt around those glyphs to the left, and proceed through the hallway. Keep going past the growths on the right hand wall and you should eventually come to an area with a bunch of windows to the right, and a couple lounging chairs to the left. Move past the window divider thing, and then... When you're about two thirds of the way down it, just say forget it, and phase straight through that thing. Just use your dimensional powers to go straight through it towards the chair that you can see through one of the panels on the left hand side. Once you have evacuated this mortal coil temporarily in order to accomplish this task, you should be, actually behind a reception desk of some sort. Or, technically in front of it, I suppose. You come in from in front of a reception desk, the receptionist sits behind it, so... Anyways, look behind the glass doors in front of you towards the aberrantly large vases, go ahead towards the one on the right and then move through the one on the right and the one on the left, kind of even with the last of the trio. Keep going down this hallway, just, straight down the middle of it, until you see the round reception desk on your right. Follow the curve of that desk along the blue mark on the ground. The line of blue-ish gray granite, rather. You should come to two more windowed dividers, but don't phase through these, they don't deserve your crazy anomalous super powers, just step between them towards the glass door that you can see. It should open up automatically. Proceed through it too another donut-shaped reception desk... Actually, this one's a kitchen I shouldn't have been so prejudiced. I apologize immediately, but that doesn't mean that I want any of the apples, and you probably don't either so head towards the bar stools. Once you're past the bar stools you should see a lit pool. It occurs to me that having a little kitchen area here right next to a pool kind of contradicts that whole thing about not eating and swimming within thirty minutes or something, but y'know what? Who cares? Go ahead towards the pool ladder and once you are standing in front of the mat that has been set in front of the mat, that has been set in front of the mat that has been set in front of the pool ladder, you're done. I-... I cannot-... I cannot imagine why they have three mats placed down there, instead of just getting one large mat. Even a permanent towel, just, something that looks better than three mats. That's unsightly.
