Candid camera? Maybe you were just there the weekend our daughter had her 16th birthday party (sleep over) at that hotel. As I remember, they had 2 or 3 rooms of 4 girls each -- thankfully with mothers as chaperones. Nevertheless, I don't think it was particularly quiet or sedate. Could easily have been mistaken for a Candid Camera episode from some of the descriptions I heard afterwards!
(I assume the hotel encouraged such rentals in order to get at least some weekend revenue!)
