They have the same packages but cheaper.
For instance, this package (click here).
It's 235 euro in Hotel Bellevue, but only 170 euro in Trabener Hof.
Normal room rates: 80-110 euro per night, double room (2007).
I met some people in the bar of Hotel Bellevue who told me they were having a good time at the Trabener Hof. They were directed there because Hotel Bellevue was booked full.
