So I'm doing a whirlwind European adventure with two friends, and I'm looking for a bit of advice. The plan is to go from Prague-->Krakow-->Warsaw-->Amsterdam-->Belgrade (Serbia)--> Croatia-->Rome
I've got the travel for the most part sorted out, but I'm wondering if anyone has any advice on the best way to get from Amsterdam to Belgrade. I haven't found any solutions online really. Also where to visit while in Croatia, I think we'll have only two days there.
Thanks a bunch!
