Can't believe I didn't mention cruisecritic, too.
They *made* our honeymoon. My husband wasn't used to my obsessive online planning yet, but the cruise is what convinced him (if only he'd gotten to that point during wedding planning!).
We did one official excursion; the "tea" at Jewell Gardens in Skagway. They picked us up on a bus (or shuttle), we had a lunch and tea, wandered the gardens (with the Alaska sunshine there's an extended growing season AND that area was a Superfund cleanup site so who knows what that did (they mentioned that)), bought some tea, it was very nice. Interestingly, their tea (or at least the kind we fell in love with) is from the east coast.
But the other stuff we did on our own or *would have* done on our own, if we'd had the money. We went to Mendenhall Glacier by getting off the ship, finding the big blue bus, paying about $5 each which took us roundtrip. We would have arranged a whale watching trip without the ship being involved, etc. Cruisecritic tells us SO much about the companies that are trustworthy, etc. The only thing that going through the ship gets you is that if their transportation makes you late, they KNOW where you are and will help you get back to the ship, even if the ship has to go. If you're on your own and YOU lose track of time (or if you're on an official tour and wander off), you're on your own to get to the next port.
But they tell you what time the ships leave, etc, so if you don't try to do *everything*, you can do your darndest to get back *well* in advance, no worries about that.
Anyway, cruisecritic is awesome. Though sometimes the
RCCL board (that one in particular, it's very odd) feels like the community board here, LOL.
