Going to Menorca next year

A thought just ocurred to me... the last time we went which was 2003 we had to pay what I think was called ECO tax upon arrival at our accomodation. The rate was a few euro's per day depending on the star rating of your hotel. Can anyone tell me if this is still payable as I cannot see any reference to it in the tour op brochure.
Many thanks for any replies...
