Disco party and strict rules

Today evening we had a so called "disco party" in hotel. Over 200 people were there, including students and guides. By the way, most of the guides are staying with us in the hotel, a small group of them have no room, but they are in the hotel next to us and they spend most of their time with us here.
I liked the party pretty much, sadly they stopped it earlier than pllaned and sent us to our rooms.
The rules are: Staying in our own rooms after 11 pm; No swimming in the sea. (and of course the olympiads basic rules: no smoking, alcohol)
The sea is polluted with oil, so I wouldn't want to swim in it either. We can see the oil pumping stations on the sea frm our window.

We live in houses with about 30 separate rooms and some guides are running around them watching for people staying out. Today I don't care, because I'm sleepy, but we will see how this will change in the next days.
