Kristin, I was wondering the same thing. Since in the brochure some balconies are colored brown and the others aren't, I surmised that the ones that aren't brown are just whatever the body of the ship is made of. I do find that odd, though, why finish only part of your balconies in teak, why not all of them??? Basically, from the look of the brochure, category B and the Grand Suite are the only staterooms to have teak?!
I will find out, but I have to wait until my June 2006 sailing, and that's a long wait! So if anyone could chime in who has stayed in the other categories (C, A, and Owners) - what are those balconies made of?
