You have a very good access to the local train-system via the hotels right next to the airport terminal:

Sheraton Dusseldorf Airport:

Maritim Dusseldorf Airport:

Martitim Airport is a new airport hotel with easy access from the airport building .

You get from the airport to the main railway station Düsseldorf HBF with train S7 within 12 minutes every 20 minutes .

To Cologne you have to changed there .

But, why not a hotel in he city with easy access to the airport ?

If you take a hotel near Düsseldorf HBF you get quick to the airport and you wife is in town for shopping and sightseeing during the day .

And you can spend your evenings in the town .

To tell you the truth: I would stay in Dusseldorf city to make my wife happy...

There is a Metro going out to the airport every 20 min and it takes 12 min from the main station.

If you take a cab that cost you around 18 Euros.

The airport is close to the city and not an excinting place to be. Dusseldorf has more to offer than a boring airport hote. My wife would certainly be upset if she finds out that the city is so close by and she has to stay at the airport...

thanks all. I think I'm getting the message about airport v. city hotel! My business contact, who will be travelling from outside Dusselford requested that I could be collected from an airport hotel. But it may be better to stay at a city hotel, and then I get shuttle to airport for collection - thus leaving wife to shop in city!
