A good way to keep accommodation costs down is by staying in private rooms, which typically cost 120–140Lt with breakfast. The most reliable agency for these is Litinterp (litinterp.com), which has offices and guesthouses in Vilnius, Kaunas and Klaipėda; the latter can book rooms in Palanga and on the Curonian Spit. Spartan double rooms in budget hotels can cost as little as 100Lt; smarter mid-range places charge 140–200Lt.
There are an increasing number of hostels, especially in Vilnius and Kaunas, usually charging 30–45Lt per night for a dorm bed; it’s best to reserve in advance. There are also plenty of campsites in rural areas; expect to pay 10–20Lt per person, and the same per tent.
