I am going to Dortmund on 27 June for World Cup game #55 with a group of four. One person in the group has reserved rooms at Holiday Inn Dortmund Hotel. I believe it is 6km from the Dortmund downtown. We would like to spend the nite hanging out in the Dortmund downtown, do you think the hotel is a good choice? I am open for hotel recommendation. Another thing is we plan to take train to Paris the next morning so maybe you can take this into consideration for hotel recommendation. Thanks in advance for any recommendation!
