My husband and I are planning a vacation to Eastern Europe in early April. We fly into Zagreb and out of Florence 2 weeks later. Must dos in between are budapest for 4 days and Munich to see my cousin for a couple of days, but we are quite flexible the rest of the time. Any suggestions on routes/itineraries would be very welcome! Our budget is ~100-200/day. Possible inclusions are Vienna and Prague, but we don't know the area well, and how easy it is to get around. Thank you!
