This new five-star deluxe colossus bills itself as "redefining the meaning of the term 'Grand Hotel' in the 21st century". With a speciality restaurant, piano café, hairdresser, pool, saunas and fitness centre, it's the perfect place to while away a wet weekend. To remind yourself where you are, ignore the aesthetically appalling exterior and check into one of the Bavarian rooms or a tower-floor suite with views stretching as far as the Alps.
