Yikes is right - $475 pp I woud be booking a 2nd cruise for that much, but I do try and book the cheap cruises so can go more often
But on the other hand, it comes out to $34pp per day - that doesnt seem too bad for the upgrade. I still think you'll love the balcony. 8 sea days - what a dream cruise that is!!! I just luv the sea days.
