i stayed in the carolina a good few years ago and i remember there being a HUGE building site being right infront of the hotel, above the water park.
we had the apartment on the top floor over looking all of the developments, and the dust, dirt and noise was constant!! 7am in the morning till about 8pm! there was no peace n quiet round THAT pool!
we had the choice to move to the monaco or somthing, but they didnt have any 2bed rooms left... so we stuck it out!
Never again would i go to gran canaria
PS! also, it was advertised in the direct holidays brochure as being excusive to direct holidays and the UK! ONLY to find when we got there there was alot of spanish guests, taking up a lot of the apartments!
