Thank you for all the comments, but they are all from months or years in the past. I notice the State Department has Istanbul on the "reconsider travel" list. I have the possibility of visiting Istanbul on my home from a Oberammergau/Israel/Jordan/Egypt tour. The main part of the trip alone will be about 3 weeks. This is already stretching my husband's time being away from his own bed, so we'd only have two or three days to explore Istanbul.
Is Istanbul reasonably safe? We would be traveling on our own - would you recommend a guide, particularly for the Grand Bazaar? We visited Morocco a few years ago and, even though my husband's navigational skills rival that of Lewis & Clark, I'm concerned about getting lost and never finding my way out. :-)
I grew up in Vegas and well understand being in a tourist town. There are some areas in Vegas that are no problem, and others that I would advise anyone to stay far, far away.
I would appreciate any thoughts, ideas, or ruminations any of you might have to share.
