Is it difficult to get taxis at the train station to accommodate 5 with luggage or should I rent a car or hire a driver to meet us there?
Depends on the train station. In major stations there will be a variety of taxis and you can find a van-type cab. In some smaller stations you may have to wait for a cab to show up or have the barista call one for you - no assurance you'll get the size you need in the latter case. If you post the names of the cities/stations, we can give better advice.
In Budapest for example you want to call a cab instead of using one of the cabs pared at the curb.
Sorry about the earlier vagueness. I pushed post before I finished with my question. I will be traveling throughout Germany.
Tina, depending on the length of the taxi trip, you might just get 2 taxis. Most of the Mercedes sedans will not handle 5 plus their luggage.
