The friends were in the room next door.
If so, that makes more sense. She was hammered and was going to try and surprise them by doing something really crazy.
They are waiting for me to come in through the front door, they'll never expect me to show up at the back door. Now if I can j-j-j-ust reach oooover here and..... wa-wa-w-WHOOOoooaaaaaaa....

Yeah, that's what I thought. For whatever reason, she decided to cross the balconies, not the hallway, and fell into the sea (which the cameras recorded).
Personally, I try to avoid doing anything where a slip results in a horrifying death at sea...for the most part.
Um, I guess it is SO much easier to climb balconies than to open a door, step into the hallway, then knock on the door of the next room.
What a maroon.
