Great, I'll try and head along then and hopefully get you there. Is it the Radisson on Herrengasse? I can see it's about 15 mins walk from the Highlander but there is another Radisson a bit further out, around 30 mins walk. I assume it's the first one as it looks more central. I'm staying about a 20 min walk from the Highlander and it's about the same time to get to the Radisson on Herrengasse.
