When in Turkey make sure you see:
Istanbul...Topkapi Palace, The Blue Mosque and the Grand Bazaar. Side Pension is a good choice to stay at.
Gallipoli...TJ Tours are fantastik!
Selcuk...is a nicer place to stay to see Ephesus then Kusadasi. Kusadasi is the cruise ship port town, can be more expensive but may be a good choice if a party is what you are after
ANZ Guesthouse is a good choice here.
Have a look at www.anzguesthouse.com
Koycegiz...is worth a trip as it is a small viallge where you can do a day boat cruise along the river that takes you past Lycian rock tombs, goes to turtle beach and you can cover yourself in mud!
Fethiye makes for a good base.
Ferah Hostel was good here.
If you have time do a boat cruise for 3 nights 4 days. They finish in olympos. Well worth!
Olympos...is set in a national park where a river runs through the ancient ruins. Kadirs Tree Houses are the famous tree houses here.
Cappadokia...is in central Turkey where the ferry chimnies are and underground cities are. It is such a neat place with such a wild landscape.
Kelebek Pension is a really good choice here.
