Two hotels (http://www.spatervis.ee/en ; http://viiking.ee/en ) near to the venue are 53-70€ per night/per person in single room.Both of these have spas and saunas, particularly nice if the weather is cool.
There is also a hotel (http://www.carolina.ee/hotel) that is 25€ (already special price for college) per person per night but this has no saunas or swimming facilities and there are only 20 rooms for two.
