We have done germany, Austria and Switzerland all on our own, several times. Those countries are lIke Driving between neighboring states so it’s not as hard as it seems. Personally I prefer Switzerland and Austria more than germany but its all great. I’d suggest you pick up Rick Steves book or books, he always has great, fun itinerarieS. And decide if you want to focus on countryside, castles, or cities. Sorry you don’t want to go to a camp...I think it should be required for every kid.
