Ive booked the Chateau De Villie icemeler, also stayed at Devamali, Navy hotel gets good reviews all very central except Chatea De Ville which is at the end off the prom and a 10min walk to the centre

when are u going and I can look at some prices

It really depends on what you are looking for. Icmeler and Marmaris are very different resorts so do you want accomodation that is lively or quiet, near the beach or further away, in the heart of the action or tucked away, self catering or half board?

I've only been to Icmeler so can only recommend accomodation there. If you give us a bit more info on exactly what you're looking for I'm sure you'll get some good recommendations
