My adult son and I will be traveling to Israel in late October. We have a 6-hour layover in Istanbul, unfortunately it is from 5:00p-11:35p. Though I don't think it would be enough time or if it would be a good idea to venture outside the airport even if we were there earlier in the day. I would appreciate advice on what we can do for a couple of hours. I'd really like to have a niceTurkish dinner somewhere. Will we need visas if this is just layover? Thank you in advance!
