@mrs12 I went to Turkey last year for CLS, so if you have any questions, I can answer them for you! Also, you should check out ARIT, they also fund advanced Turkish studies over the summer.
As for the questions you asked - we were in class M-F from 9-1, and we had office hours we could go to as well. You have cultural excursions throughout the summer, and you will have lots of time to spend with your host family and your language partner (you have to meet with the twice a week for at least an hour). You can travel on the weekends and over Bayram. However, my suggestion would be to try not to travel too much, if you do go, because you an fall into using too much English if you do.
