Just a tip
If you are the east coast some of the best (non-stop) flights put you in Munich in the AM.
Do not schedule your delivery for the same day.
We did and I naturally could not sleep at all on the plane, by the time I was chatting with the (very cute) receptionist and trying to do paperwork I was near incoherent.
Fly into Munich in the AM
Take S-Bahn to hotel
Go out and drink way too much amazing fresh tasting German beer (mmm)
Drink a ton of water; pass out early
Wake up early refreshed and begin journey
