We stayed there before our cruise.... But it has been quite a while now.
We were lucky and got a 1br suite. It was really nice! And, we loved the hotel and the location. The van service to the ship was excellent.
However, it is an older hotel, and I am not sure that all of the smaller rooms are as nice as our suite was. When we made our reservations, they were getting mixed reviews.
To find the cheapest Rates, go to the Radisson site, and then keep navigating till you see ALL available rates. (at least that is way it used to be.) Then you will see any promotional rates that they might have.
The new RonJon resort seems to be a highly recommended place to stay.
If you are arriving late, and leaving early for your cruise... Then you may want to find a cheaper room nearby, since you will not really have much time to enjoy the Hotel, Pools, etc...
You could go online to any Travel Site and pull up Cape Canaveral and see what all is available.
You should really post this over on the Cruise Board!!! There is sure to be some good info about nearby places to stay. Maybe a Mod will see this and move this thread over there?
