The PanoramaCard gives free bus and PostBus travel in the region (as far as Spiez and Interlaken) as well as a free city walking tour. Also included are discounts for lake cruises, the Thun & Spiez castles and mountain transport.
The PanoramaCard is given to each guest staying overnight and is issued by the hotel on your arrival. It is valid for the duration of your stay, including the arrival and departure days. The card also means you can hop on and off the local buses without having to worry about using the ticket machines.
