How did you book and got the upgrade ? Virtuoso, LHW ?
I will be doing an Alps driving tour (Austria, South Tyrol, Switzerland) in August and am thinking about staying at Badrutt's Palace for a night or two once in a lifetime. Having been a winter regular to the area for over 25 years I never stayed there as I am more into hotels like Saratz in Pontresina or the Kempinski... But for 220 Sfr per single std room it might be worth trying to stay at that Grande Dame...
