Hello Flyhigh,
I think the hotel in Caddenabria is used for the New Year trip. I stayed there last year with Leger and had a great time. Well worth catching the ferry just down the road to Bellagio- wonderful shops.
The Bernina Express was magical, loved the snowscape. Lugano is glorious and one of the best shops was a department store with a brilliant basement full of wonderful food.
Enjoy,
Jan
