Iberostar Ciudad Blanca - on the beach, four stars, right near to the main tourist centre, easy walk into the port.

Platja d Or Hotel is all inclusive and for adults only. You can see it in the Thomsons brochure and read reviews on HT.
Although I have never visited, friends of ours have been there 3 times this year and say it is fab and has high standards.
Think I will give it a go soon!
