Sorry to disagree Webray, but anyone staying at the Radisson is welcome to park there. I have done so 2X myself, and also heard another cruiser who called the hotel to make sure a "cruise package" is not needed to get the parking. The hotel WILL ask you to park your car in a specific area so as not to take up the spots in front of the rooms while you are gone.
For anyone on a 7 day cruise this translates into an 70.00 savings! So you could look at it as a almost"free room"!
