Our guide was outstanding, informative, helpful, went out of her way to help and assist each of us. I was picked up and taken back to the airport and assisted until I got my boarding pass, just as the trip notes indicated. I believe we got to do everything.
Truly enjoyed the tour, also the other tourist were all friendly and nice. Group got along well.
I would have paid extra to have had only two persons to share the two overnight train rides with, evidently that is an option on the train.
