You don’t say what sort of hotel you are after, only that it’s the so called ‘Biker friendly’ hotels (or ‘digs’, to use the vernacular) you are after. You could try:

Still not sure? OK....
The hotel is in Bad Mitterndorf. It’s probably not the only one there, it’s just the one that has tied it up with the popular ‘biker hotels’ listed by Tourenfahrer. Put the town into a Google search and add the word ‘hotel’ too. Surf around in the 15 or so that pop up and select the one that sets your juices running the fastest.

Job done...... all it requires is a bit of effort and a touch of imagination, not least as you’ll be able to imagine the sort of ‘Biker friendly digs’ you have in mind, much better than us. By the time you have done it once, the other five towns you have asked for will be a doddle. Failing that, wait for some bloke to tell you where to stay. That he likes to spend tuppence and get pissed each night with 30 blokes from Hamburg, you’ll discover only when you are there.
