Very inexpensive rooms. Familly run hotel and restaurant. 15 km away from Vaduz, regular hourly bus service to all parts of Liechtenstein.
There are a few hotels in Liechtenstein, but they tend to run on the expensive side. There is one youth hostel located in Schaan, but it closes for the winter. You will probably be able to find cheaper accommodation in neighbouring Feldkirch, Austria.
Camping Mittagspitz is the only full-service campsite in the Principality. It offers excellent facilities, a friendly reception and a fabulous reasonably priced restaurant. There are three other camp grounds in Liechtenstein. One in Bendern, one in Vaduz, and one in Triesen. All are pretty much full year round.
