hello BJBZ and welcome to TA...
you will get far more useful information if you post a question that indicates you have done a bit of research AND if you give some more info about yourself & your current trip plans.
how many kids? their ages?
how long is your trip? how much time do you plan to spend in Germany?
where do you want to go? what do you want to see? what do the kids want to see?
what is your budget?
where are you from - believe me this makes a big difference in terms of the suggestions that may be made (please update your profile location)
post your tentative itinerary and the regulars will have something to comment on - at this stage you are asking them to read your mind.
