Looking for some reviews and feedback from anyone who’s used vacation by rail and, hopefully, specifically the grand imperial cities route. I’ve never been to that part of the world and I love the romanticism of riding the train.

Good idea or bad idea to use them? And if the answer is bad idea, what other tour package would you suggest? I have some flexibility for cost. It’s just me traveling so having a tour guide/guided tour is important.

Thanks in advance!
