Trip starts from the bus station in Żywiec on the 'fourth morning' (nie, nie tak - morning of the 4th), from where the coach IS to take us to the guesthouse
'Łupkowskiej' (?) passes. 'A' THE trip is FOR three days. Upon arrival, we have (accommodation for the) night, (and intend) gaining the summit the next day. After descending from the mountains, we WILL go to sleep again, and EARLY the next day 'from the morning' (niepotr) WE WILL 'to' (niepotr) return home.
On the trip you should take some clothes to change, and food on the bus route and 'travel to the top' (cos tu nie tak) .
I think we WILL spend good time there. Reply as soon as you can, because
in a few days THEY may have already run out of places.
Greetings from 'Sopotnia' (a gdzie to jest?)
