We have either six or seven nights to spend in Bulgaria after spending five nights to Krakow (including a day trip to Auschwitz, already booked) which is booked except for our flight to Bulgaria. Wiz, never flown this airline before, has cheap flights.
Since we are going in April, I think we can skip the Black Sea. We mainly want to see Sofia, Plovdiv, and Rila Monastery.
So, how does this sound?
1st day: Fly from Krakow to Sofia
2nd day: day trip to Rila Monastery (possibly rent a car but there are tours.)
3rd day: Day in Sofia
4th day: Travel to Plovdiv and sleep there.
5th day: Plovdiv
6th day: Travel to a Western Europe city for a day or two we haven't been to fly home to NYC.
Thanks for any guidance.
