The scenery on this trip was stunning and the trip is worth it simply for that. All other aspects of the "tour" left much to be desired. The guide was not a local and spoke so quickly such that you couldn't understand what he was saying most of the time. The Interlaken stop should be left off the tour as it consists of 20 minutes of walking down a strip of tourist trap shops. The bus was uncomfortable simply because they put way too many people on it for comfort. I think they must have packed at least 100 people on it. My companion and I opted not to pay extra to go to Jungfraujoch to save some money. I still found the scenery to be breathtaking and don't regret that decision though I'm sure the top would also have been spectacular. At one point the guide basically pushed us off the train for a 30 minute stop at Wengen since we decided not to journey up to the top. When I tried to explain that we didn't want to get off here and would rather spend all of our time at the next stop up at Kleine Scheindegg, he said there was nothing up there (i.e., no tourist shops) and we would have too much time up there. However, he just didn't understand that we were there to get out in nature and not spend our time looking for trinkets in the shops. I was highly irritated by this, but was happy that it meant we didn't have to deal with the guide and the rest of the 100+ group. If you don't mind the higher cost, I would recommend doing this trip on your own.
