Up until now, your character was having a reasonably normal day. But for whatever reason, when they walked through that doorway, or spaced out for a moment, or even just turned around and blinked, they found themselves here instead of wherever they should be.
An enormous pool takes up much of the main room, which seems to be the relaxation area of a reasonably-pricey hotel. Beach balls and various other inflatable pool toys dot the water, and enclosing the tiled floor on two sides are glass walls, allowing one to see out onto the sunny, landscaped lawn. In addition, there is a doorway clearly marked "Sauna," right next to two bubbling hot-tubs.
On the pool's other side stands the Fountain, which is a large statue of a wide-mouthed fish spewing glitter into a surrounding basin. Around it is situated a number of tables and beach chairs, and beyond that is a cafe/bar with almost every type of alcohol imaginable, as well as coffee, several types of cakes, and a pile of small sandwiches. One of those cigarette vending machines is there too, although it doesn't seem to need any sort of actual money. Someone has kindly left a lighter on top, but it appears to be the only one available.
If someone really wanted to, they'd find it's possible to leave the pool area, which leads to a hall lined with nicely furnished, lockable rooms....
And ah right... this time there is no need for punch, because there is already a twist to the fun!
-If you so choose, not only does your character find themselves inexplicably in a new place, they are now the horrified proud owner of a body that has been turned into the opposite gender.
-If you can make plans beforehand, feel free to skip the gender change but bodyswap your character with someone else's, either before or after they meet up.
-Or, don't mess their bodies up at all and just see what happens in the setting. No pressure. xD
-Everyone is wearing whatever is deemed appropriate by the player. Let's see some bikinis on the new ladies, shall we?
First rule of the game is have fun. Second rule is don't be lame. Any and all characters are welcome, and powers/abilities are available so long as your threadmates are cool with it. :)
