"You have to take a public bus from the second floor. Don’t follow the shuttle sign. You’ll have to come out and there is a big outdoor atrium and you go one more level up to the street level. I took the ride late and the bus driver didn’t bother collecting fare. It also looked like that it’s routinely people jump on the shuttle from the back door and not sure they paid either. You can buy a ticket at the hotel front desk when you return to the airport. Given is much cheaper than the property at the airport (and you have to walk to the big atrium anyway… and MUC is a big airport), I’ll go to NH again!"
