Radisson Worldgate is 1.83 miles from AKL, Best Western is 2.3 miles, once you get to Sherberth Rd all the directions are the same. I would let price be your guide, not distance.
One thing I forgot to mention, if you get one of the higher floors at the back of the Radisson you can actually see the Tree of Life, and if you are there after dark you may catch some fireworks also, a nice teaser for the kids.
