hi there i am mostly a lurker but feel i must reply t this one. i know it may be a bit late but better late than never. i booked independantly and the mersoy hotel has a few different buildings.
mersoy bellavista - adult only with spa and all extras - all inclusive
mersoy exclusive - 2 buildings in the same area
mersoy exclusive oriental suites which are roughly 100 yards way from the exclusive away from the main road.
the oriental suites are an add on from what you could call overflow from the exclusive. its is supposed to be apartments but they do cater for the all inclusive and there is a restaurant where you go to for food etc.
i got put in the oriental building and i complained as all the pictures etc were of the mersoy exclusive itself. the pool area and restaurant i personlly didnt like and i did get moved to the mersoy exclusive building.
i spoke to the manager and he did tell me that as off next year the oriental building will be apartments for b& b only possible half board.
hope you get somthing booked.

look in the first choice turkey brochure, they are doing the mersoy oriental from 2010, b&b, not cheap either!
