If hyou will be there any time in July/August period, Göçek will be pretty crowded and very hot.. There are plenty of bays couple of miles one from the other one, all are beatiful and safe. If you don't want to spend yr entire week in Göçek and Fethiye, you may either go to the east; Kalkan,Kaş, Kekova or to the west, Ekincik, Marmaris, Çiftlik. East will be even hotter and you will have to
motor 90 % of the times, meltemi dies to the east of Ekincik. The
route to the west will be a bit fresher and you may find a bit of more
wind.
Have fun, either way I am sure you will enjoy
Turkey..
Cheers
