My wife and I will be taking a cruise out of Rotterdam at the end of September. We would like some recommendations on hotels that are in close proximity to the port. We only need it for one night, and would prefer something reasonable, but clean, decent, and in a safe area where we can walk. A few months ago, someone on this sight recommended the Tulip hotel, which might be just fine. But we are open to maybe another suggestion or two. Again, we don't want to stress getting to the port the following day. Any suggestions out there?
