Thanks for all the great replies.
I kind of thought that the actions outside the disco would not warrant being labelled as "rude behaviour" necessarily but it wasn't something we saw every night. In fact, we saw very little sexual activity in places that no one was supposed to be active in. Come to think of it, we could always get a jacuzzi bed every night, no matter what time we got up there.
We popped into the disco late one night "on our way home" from the roof top jacuzzi beds and saw about 6 - 10 couples having sex right in the disco - why bother with the playroom! lol.
It was a very quiet week and we had a great time. We are not party animals by any stretch of the imagination and we were not offended by those who want to have some "fun" when and where they choose.
The "rules" are posted all around the resort but they are not necessarily adhered to, nor did we see any "security guards" stop anyone from having sex on the beach beds during the day.
