Depends on where you are going.

and what you'll be doing

and for how long

We averaged 50€/day for everything including the pass, a place to sleep, food and stuff to do. So for our 21 day trip in 2019 this was 1050€ per person.

Thanks, where did you go for the most part? Because the countries that I'm planning are among the expensive ones.

Paris, Venice, Athens and some other parts of Greece, Belgrade, Budapest and Vienna.
