It's been awhile since I've done this (and forgive me if this has been covered, but I can't find it). It seems like my best choices into town are the train or the Lufthansa Bus. I understand that my hotel is next to a Lufthansa Bus stop. Is one method preferable to the other? And, btw, since I'm flying Lufthansa, do I get any sort of discount if I take the bus?

Thanks!
