Cheap Hotel along Kiel Canal
A really cheap alternative along the Kiel Canal is the Burger Fahrhaus in Burg.
Burg is situated about 10 km NE of Brunsbuttel and about 2 km from the canal, but the hotel is along the canal at the ferry. It is a German/Chinese restaurant, probably with Chinese owners. The restaurant (with canal view) is OK, the rest of the place is a bit run down.
There are about 4 rooms and you have to share the bathroom with other guests. The rooms are basic, no TV, no internet but with a bed and heating.... Many guests are shiplovers from Germany, Netherlands and Scandinavia.
I stayed there earlier this year and paid 30 euro's per night for a single room including breakfast. Not bad when you only need a room to sleep and recharge your camera.

In the summer, you have to book well in advance!
