The following is a copy of the ADASS'97 page:
Sonthofen is situated about 200 km south-west of the Munich Franz-Josef-Strauss International Airport. There are direct trains from Munich Main Railway Station to Sonthofen roughly every two hours throughout the day, and trains from the airport to the railway station run on a 20-min. schedule. A taxi from the railway station in Sonthofen to the Stern Hotel costs around DEM 10.
If there is enough interest, we will arrange to have a travel office desk open at Munich airport for ADASS '97 participants on Sunday, September 14. From here you will be able to buy your train ticket to Sonthofen, and the travel office will also be available for more general travel information. Participants who would like to make use of this service are asked to send email to email@example.com with the following information: flight arrival time; whether you would like a first or second class, single or return ticket (prices range from DEM 52 for a single 2nd class ticket to DEM 156 for a return 1st class ticket); means of payment (cash or credit card) and any other travel questions you may have. The travel office can also help with the reservation of rental cars but deals are generally more favourable when the reservation is made from abroad.
September in Bavaria can be very pleasant, but there are no guarantees! Days could be as warm as +16-18°C, but evenings are always cool. Please come prepared for both warm and cool (and rainy!) weather. (And don't forget your swimwear: the hotel has got one indoor and one outdoor pool.)
Lunch and dinner can be taken in the hotel restaurant. A three-course lunch or dinner (or buffet lunch or dinner) costs DEM 30. A buffet breakfast is included in the room price.
There are also a wide range of restaurants in Sonthofen. The town centre is a 10- to 15-minute walk away from the Stern Hotel.
