We went to Marelen in October 2007 for 2 weeks during half term.  The holiday was great but some bars & restaurants were closing for the end of season.  It was quiet but pool was great and the beach was lovely.  We had about 3 days a rain  which wasn't nice.  I would go back again as the hotel was lovely as were the staff and the beach near by.  But we would not go at the end of the season.
