We also stayed at the Radisson. There was a code that we used...I think it was "Fall"(they would know). But we got our room for 59.00 from what I remember.
Also, I guess you're supposed to book the time you want them to take you to the ship. Everyone wants to go at the same time! There's a rental car agency that's connected to the hotel. We just walked over there and they were also taking people to the cruise ship at no charge.
Hope this helps!
