I'd like to go trekking in the Tatra mountains in Slovakia, and sleep in mountain huts.
Do I need to make a reservation before the trip? Or can I reasonably expect to always get a place to sleep (even on the floor)? I've heard of people turned away from mountain huts in Poland because there were no free places, and I'm a bit anxious about that. At best I'd sleep in my tent, but AFAIK this is not allowed in Tatra.
