I agree with Mark about the safety issue - never leave your child alone on any veranda. Having said that I prefer the Navigators as well. They are more cozy to me than a regular veranda. I also love the padded bench - great place to relax with a good book.
The other things I like about them is there proximity to other things. You are at the back of the ship so a quick trip up to Topsiders/Beach Blanket, Scoops, Palo. In addition you get to have your safety drill in the cool comfort of Animators Palette!
