28 Mar 1996 I agree, meals area big issue for a lot of people. I recommend that people rent a car if possible. With a car you can also visit the Rhine Valley which is only a 30 minute drive from where Mother lives. Make car rental arrangements in the US before leaving, and check around for deals. And try to find a place to rent while in Germany where you can prepare your own meals.
Groceries are readily available at local supermarkets.
This way you will have most of your needs met. You wanted travel tips. I've stayed in Dorndorf twice, and the main obstacle is food, especially if you're a vegetarian. Try to find a place that serves meals. I also understand that if you call the house, they'll know.
