Sorry for the delayed response! I must have turned off notifications for replies and just now remembered to visit again.
Yes, sadly it is a guided tour, so I am limited a bit to what we can do outside the itinerary. I wish I had been able to go on a photography tour with National Geographic that was offered at one time, but I'm taking what I can get.
I'm at work at the moment, so I'm not able to dig through my kit and list everything. I'll try to update this evening! I'm loving all your responses so far, though.
Edited to add:
We are going in June. Leave Atlanta on June 8 (my birthday, so it's kind of the best birthday gift I could have ever asked for!)
