We found a company, My Day Trip, that would pick us up at the end of our Eastern Europe tour, drive us to Lake Hallstatt for one night and on to Cesky Krumlov and then on to Prague. Has anyone used this service and would you recommend them? They service most of Eastern Europe.
Do a search on this forum for MyDaytrip. There have been several people enthusiastically recommend them. (We're going to try it this spring.)
Ask on the Trip Advisor forums. Do they have reviews there?
Yes and yes. My daughter and I used them for transport from Venice to Zagreb, with a stop for lunch in Ljubljana. I am not exaggerating when I say that it was one of the best customer service experiences I have ever had. Period.
