Hi haven't done the full tour but Ephesus is truly amazing site.Also Pamukle which is normally taken in as it is pretty close (have your swimming gear handy) unbeliverable natural phenomenal.Staying in dalyan you are so close to the famous turtle beach and the thermal mud springs plus many more places of interest

ive been to ephesus & marys house which was quite good, and ive been to istanbul twice and we are going back again in may, its a fantastic place, we loved it, but theres so much to see you really need 5-8 days there alone, ive got a thread running on all the things i saw in istanbul if you fancy a read and ive put a lot of photos in the gallery too
