Anyone been to Germany? Worth going?

Should you go? Uh, yeah!!!
I was stationed there twice and would head back in a heartbeat!
The 1st time, I was young and single. Not going to get into the details, but man did I have a blast.
The 2nd time I invited my grandfather to come visit.
He was a WWII veteran, and was part of the detail that wired the bridge over the Rhine in Remagen with explosives. I took two weeks leave and I took him all over the country. I'm glad I did it and you could tell he was too.
You have the best host too. A Major in the Army! She'll have access to places you wouldn't normally have and she'll have a car. Trains are cool, but not so much when you have to share with a bunch of people.
I'd say if you don't go, you're robbing yourself of a once in the lifetime experience.
I understand wanting to stay close to the house, but every now and again, you need to spread your wings and get outside of your comfort zone.
