Bus was prompt. Best seats filled by people who boarded in Zurich. So understand you probably won't get a seat up top. Beautiful scenery with good descriptions. We were fortunate to have a sunny day. Tram and cogwheel train were great. On the train down sit in the low seat section, left side for the best photos. A few young people (30/40 yr olds) in our group felt the effects of the altitude. Drink lots of water prior to the trip, it helps, also breathe deeply and pace yourself. Ice cave was interesting, loved the piano. Long day but worth doing.
