Yo homies. recently got a divorce so I set myself on a european trip. flying into amsterdam, headed out the next day to Croatia, then montenegro, belgrade serbia and lastly sofia bulgaria. I could also move that around. staying in hostels. Looks like everyone is on a smattering of different currencies. anyone have any suggestions? also I was thinking of brings some euros and dollars but mainly using card where possible. I know eastern europe is a little different but those who have been tips are appreciated. I'm also not super green on travel
