> What did you do once you arrived in Budapest?

You will be perfectly fine staying in Budapest with just English; you can learn hello, please, and thank you to be polite. This goes for most bigger European cities, outside of France I guess.

Even France you can survive with English, just try some French and ask “how do you say” a number of times.

French people are quite friendly if you don’t exhibit all the worst symptoms of stereotypical tourists.
