How close are you staying to the track?
I guess August is busy due to the popular Oldtimer & VLN events.
We started off at Altes Forsthaus just up the road from the entrance, but we were paying about £20/pppn for a room with 6 small single beds and one bathroom.
The place we stayed at for year's went downhill when one of the brother's passed away. He seemed to be the motorsport fan and loved to see all the cars in the car park.
The remaining brother & his wife don't seem to care, and will close the restaurant if they don't feel up to cooking that day.
Since found a cheaper & better place, with another motorsport fan, who'll just locks up and leaves us with the keys to the door/garage and bar/kitchen (for drinks/snacks, rather than meals).
We now pay about £40/pppn but we all have our own en-suite twins/doubles with wi-fi and cable TV.
Contact Jens at Hotel Gran Tourismo in Kaltenborn if anyone's interested.
We're planning on the 4 day early May sessions (full days Thur-Sun), and will probably come down the weekend before, do a bit of touring to Frankfurt/Munich/etc. before heading to the 'Ring for the Wed evening. Then head home the following Tuesday.
