>>1257518I have been to Friedrichshafen and I have been to the Zeppelin Museum. There's also a Zeppelin Vineyard there, Zeppelin University and Zeppelin you name it.
As far as I understand, it costs a few hundred Euros to go in a short flight over Lake Constance and see some of the sights of the lake which borders Germany, Austria and Switzerland.
If you're from the United States, then the main cost will be the flight to Germany from whatever backwater you're from. Best options are either to fly into Basel/Mulhouse/Freiburg via Frankfurt with Lufthansa, into Zürich with Swiss, or perhaps into Munich with a variety of airlines, like Lufthansa.
But if you're from Europe, just take a budget airline or the train.
