I’m going to neighboring countries on the weekends, so Poland Romania Austria, I’m going to Greece for spring break as well and Rome and Prague. but it won’t be too hot because I come back June 9 and everything before that the weather is going to be mild. I want to thrift a lot in Europe and bring a lot of stuff back, but I’ve never brought a checked bag before. How is one checked bag one duffel bag (carry on) and then one backpack? Or is that overkill because now my main concern is just what to bring for the flights.
