In reply to Kate Smith:
Not a recent report, but when I went to try to do something similar about 15 years ago it was a nightmare. Beautiful area, lovely helpful people, but trying independently without speaking any Polish, to book huts in advance or on the day was nigh on impossible.
One hut we tried to book in advance, we were offered a date 2 months away.
One hut we turned up at on a very cold wet day about 3:30, we couldn't even try to check in until 5pm, by which time there was a queue/scrum of about 150 other cold wet walkers. A helpful guy in the queue near us who spoke a little English helped us check in eventually, we then had to queue again to try to get a blanket or two, there were far, far more people than beds so huge numbers were sleeping on floors, on tables, every corner of the corridor so it was almost impossible to move in there or use the facilities. Food was great if you like tripe soup, we didn't, and queuing to eat with so many people and so little room was another challenge.
Hopefully things have improved, in that it is now possible for an independent to book a hut in advance, and unless you speak Polish, hopefully more people will now be speaking English over there. If so you'll have a great time, it is a lovely area.
ps. I am a very experienced hut user in many countries around the world, just in case I came across as anti-hut or a bit of a wimp!
