My wife and I will be taking the April 29 Best of Eastern Europe Tour. After the tour ends we plan to travel to Vienna for a few days before returning home. We are thinking of taking a taxi or van as train travel will take significantly longer. There appear to be two choices, Ondaytrip and GoOpti. Has anyone used either of these companies? Are there other options that might be better?
Also, if anyone who will be on this tour is also heading to Vienna, we'd be interested in sharing a ride using one of these services.
