At the end of March, we will fly into Munich on a Wed morning, travel to Oberstaufen,and fly out of Munich on Saturday morning. We are planning to rent a car, since our time is so short. We wish to see King Ludwig's castle(s), Zukspitz, typical small towns--the terrain which characterizes this area. Suggestions? We'll be staying at Mondi-Holiday, which I understand is walking distance to a small town. We'd appreciate any suggestions! Please advise if traveling by train is wiser. Our budget has limits! Thanks.
