We had trouble in Magaluf 5 years ago.
Last minute deal for 6 of us in a hotel full of older couples (no families / children).
More like a Saga holiday!!
Stereo was confiscated on the first day even though it wasn't loud.
(I should know - I am a police man!)
We all had to sign an Official warning on the 3rd day.
(This may have been due to me throwing up over breakfast in front of 200 guests and being found unconsious in the lift shortly after...)
Some of the more fun loving older gusts got behind us as they enjoyed the way we livened the place up and a petition was raised to keep us in the hotel.
Just about managed to last the week!
4th year in a row in Ibiza now and we always make sure we are in a young and lively resort.
Enjoy your stay.
