Hope this is not too late to be of any use. New to site. We were upgraded to a Penthouse suite on our last Alaska cruise on the Diamond in June 05. It was wonderful, and made the trip even better. The balcony is double size, with wooden furniture instead of the plastic stuff on other balconies. We had a large round table, 4 chairs and 2 lounges. Another perk that you might not know about is that you can order ANYTHING on the dining room menus, not just the regular room service menu. We enjoyed a wonderful meal on our balcony while cruising the glaciers. Another extra is you get to use a lounge area while waiting for disembarkation instead of waiting with the masses in the common areas. Don't think we could swing this level of accomodation if we were paying for it, but it was a great experience. We are booked for a mini-suite on our Sept. New England Cruise, and secretly hope for another upgrade!
