I had clients stay at the Radisson at the Port in August, and they liked it a lot. I haven't seen the hotel, nor any of the others you mentioned, myself.
Radisson has shuttles going to Port Canaveral every half hour. My clients reserved the 11:30am shuttle, but were in the lobby early, and were included on the 11am shuttle instead. It's a van, pulling a trailer that has the luggage.
