We are arriving dusseldorf on 6th may for a week for DRUPA 2012. We decided quite late on this trip and hotels in dusseldorf seem to be too expensive. We are looking for hotels below £50 a night. Must have a public transport facility nearby for going to the trade fair. It would be great if it is in the network which allows us free public transport on the messe ticket.
I was thinking maybe cologne or Essen or any other suggestions are fine. Please recommend some budget hotels accordingly.
