I wasn't impressed with the Raddisson. I really wish I'd booked our pre-cruise stay at AKL. Enjoy the pool, eat at Jiko, Boma for breakfast - then get on the ship.
The pool WAS big, but lacked a slide. The room was ok, but except for the luciously appointed bathroom (we had a suite) not impressive. The resort seemed a little run down around the edges (though our room was cleanish). The restaurant wasn't good and was overcrowded. There were far too many people going on "other" cruise lines looking for a party hanging by the pool for me to feel comfortable with my kids there for long.
