A contingent of 20 double rooms and 15 single rooms is reserved for us in the hotel at a special rate - 199 EUR/night and 159 EUR/night, respectively, including breakfast and access to the recreational area (swimming pool, sauna, whirlpool). Please book directly with Strandhotel Seehof if you wanna make use of that option and mention you are an AK Klima participant. Once the contingent is exhausted, there might still be the option to stay in the hotel; note that this depends on availability and that the price might be higher.
Alternatively, there are smaller bed & breakfasts and a campsite nearby. Here are some links to those options.
