We're from Seattle area, so this worked fine as last-minute cruise. This was our 17th cruise (with 3 more booked---husband is a cruise addict) but first on Royal Caribbean. It's also the only one we've done with just each other; we've cruised with close family, kids, extended family, co workers, and friends, but never just the two of us. It was great fun, and changed the dynamics of the cruise for us. We interacted with other passengers more, found some great friends to hang out with, and plan to do it again. At the end of the week, we love each other more, so I call it a success!
We've sailed on NCL, HAL, Celebrity, and Princess previously. I'm not going to talk about the ports of call, since the ship is done with Alaska for this year and you're not going there...except to say, if you get the chance to cruise to Alaska, TAKE IT.
Our cabin was the smallest ever, not much bigger than a walk-in closet, but it had a surprising amount of storage. Even having packed warm gear and rain gear and formal wear, and I may have shopped just a little, it all fit with space left over. Our cabin steward kept the place clean, and was friendly. My only (mild) gripe was that it took 2 days and three reminders to get some ice.
