I am a first time cruiser going to Alaska on the Royal Princess round trip from Seattle in September. We are debating upgrading to a Penthouse Suite from the mini suite we have booked. I noticed there aren't very many of these rooms on the Royal but most are still available. Is this common? Do people wait and try bidding for these rooms or are these room just not a great option? The amount to upgrade is a lot so I just want to make sure it would not be a waste of money to move. The extra room and large balcony are the biggest draw. Though the priority disembarkation at the ports seems like it would be huge add too. Which room is the best in those available in you opinion? Appreciate any insight anyone has one these room!.
