You did better than my wife and I and elder daughter managed! We never did
work out what ticket to buy nor find a kiosk apparently selling them so
walked everywhere, not a big problem, we found.

They used to be everywhere, with the letters RUCH on the top. Did nobody
tell you?

They still are, and it explained in the guidebooks what to look for
(but, alas, not what to ask for, and I should have got the hotel to
write it down for me, but we managed!)
