Hop On Hop Off City Sightseeing Munich (Red Bus)
My headphones were not working so my wife and I shared hers until another set of seats became available and we could switch (and they worked in the new location.) The tour is good though a little pricey, but you’d pay the same amount with the other cruise line. A suggestion would be to do the City Tour then start it over again until you arrive at Marienplatz, for example, and save your feet from walking it!
