Wife and I connecting in IST flying TK Biz BKK-IST-ATL on 7/31. We have about a 9 hour layover (5am-2pm). I was originally planning to take the 8:30-11 tour (Bosphorus cruise seems way overpriced). We have been to Istanbul before and seen the main sites. Is it worth getting a visa and dealing with all that hassle or should we just hang in the lounge and find a place to rest, eat and relax? Any thoughts from those that have been on this tour or had this kind of layover since the visa rules changed? Thanks.
