Questions:

a) I understand that there are 2 actual "tickets"- one if the paid ticket for the train travel and the second is the paid seat reservation (to put it another way, can you get away with the paid seat reservation)?

b) I understand there are 3 classes on this train- I read the web site for the information on second class vs first class vs excellence class. What would you recommend? We are not really connoisseurs of food or alcoholic beverages. We are 4 in our group - we want to sit together on one side of he aisle. But we want the best view possible. Is there a special section of the train with special views- ie glass roof/ceiling as well as windows from roof to the floor?

I guess food is included in the ticket for excellence class, but one can order and pay for food in the other 2 classes of rail travel. I guess there is no dining compartment in first and second classes- there is only a dining compartment in excellence class.

c) one of 4 members of the group has medical issues. If she can not make it - can a medical certificate from a doctor be enough for cancelling all 4 passengers tickets and getting a full refund?

d) we will be based in Zurich-so it is worth taking the Zermatt to St Moritz complete route- or should we take the Zermatt to Chur route- ie anything of significance to see between Chur and St Moritz.
e) one of the party is mobility impaired- what does it mean per the web site that there are special wheelchair tickets

f) we feel uncomfortable buying tickets directly from the web site- are there any travel agents in Canada (where we live) who specialize in selling train tickets- especially if those travel agents are Flyer Talk participants..
