Listen out for cheerful chatter, particularly female giggling or laughing, some 'get you in
the mood'
music, or, one of my favourites, the sounds of a
woman's shoes being flicked off.
My advice to you is, never post, on a public internet forum, the name of a hotel where you intend to record sex sounds.
BTW, I've just read some of the reviews, and some members here would have a field day (and night) in there.
As well as obtaining lots of corridor sounds, I would definitely bug the pool area, and perhaps lurk in the café
and bar to catch some sexy-talk - you might even get to record a hot hooker attempting to pick up men (just
watch out in case she's carrying a
chainsaw.

)
I really don't have too much negative to say about the Rio, it is about as clean as any other budget casino/hotel, the rooms are certainly large enough, but the walls are paper thin and the folks next door to us were either killing each other or having some pretty agressive sex from about 1:00 to 3:00 AM.
