In Poland they'd reserve a seat on the tram if they could. People book tables in pubs and even reserve graves!
Dorms are often unstaffed at this time of year, or rented en masse to organisations such as the Malta Festival.
That's what I thought. I've checked Jagienka, Jowita, and Zbyszko so far , and they all told me they don't have now and to check again in September or October as some rooms will be available, But that's is just illogical, if they don't have now (summer break) how they're gonna have in Sep, or Oct (fall semester) ??!?!?
