Would I recommend this particular adventure to a friend, in a word no. However I would caveat this with I had a great time and I would definitely recommend G adventures as a tour group and these three countries are definitely worth visiting. It's only a couple of small points that need 'ironing out' which is understandable considering the relatively new itinerary that has been created. Our CEO minty ensured a smooth tour and I suspect that another tour guide would have handled the issues not as effectively. Thank you, G Adventures, for a wonderful once in a lifetime experience.
