Stranded in Munich due to snowstorm - any help appreciated

Hi all!

My boyfirend doesn't have reddit so I am posting to ask for help for him. His flight to Bremen aroun 6pm got cancelled today and he's been there most of the day trying to figure out a way here. His replacement train at midnight got cancelled 15 minutes before due to snow and ice. I know many people are in the same situation. A few of us are calling to try and get a hotel room and everything is booked.

Is there anything we can do in this situation so he can have someqwhere warm to sleep, or somehow reach abck the airport from Pasing where he is now?

Thank you all for any help, it is greatly appreciated!
