That said, all those cities can easily be done by train. If I were you, I'd be searching for YYZ-KRK on LOT and BUD-YYZ on LOT or TK, and do the rest by train. You'll probably save enough in fees to cover the cost of the trains.
Thanks! Procrastinated too much and it's peak summer travel period so I am trying to work with what I can for flights/trains. Unfortunately we cannot start in KRK but that was the first choice.
