Hi Chrissie,
There will be a rep meeting you and another passenger in Zurich and you will both be transferred to the hotel where you will meet up with the rest of the group and tour manager when they arrive, so giving you a chance to relax and enjoy a glass of wine before the others have even left the UK!
I cannot give you the name of the passenger but if you post a thread in 'Say hello to other single travellers' the other passenger might see it and get back to you,
Hope that's OK,
Ben
