I'm looking at doing the Mongolian Wilderness trip, but wanted to do the 19th June departure, as the Nadaam Festival runs almost immediately afterwards. However, when I look onsite, the tour is booked up (serves me right for not doing enough forward planning!) . Is it possible to register on a waiting list in case someone cancels their trip? If not, does the tour that starts on 10 July (or any of the others around that time) run slightly differently to allow people on that trip to spend some time at the festival, given that the festival is on during the first few days of the trip?
