Hi, I've cruised a dozen times, mostly on RC and have a B2B booked on Adventure (Southern Caribbean) for later this year. But I've been missing Alaska (cruised there 3 times before) and wanted to try Celebrity, so I've booked Century for May 2014. It appears that the regular balcony cabins are the same as the Concierge balcony cabins. My question is what are the differences except priority boarding. Would I get priority boarding anyway because I'm Diamond with RC? Any information you would care to share will be appreciated.
