Ah...the ship is starting to fill up. Finally. The solitary confinement is ended. Company awaits.
I'm happy to share whatever cruise wisdom I may have gained on my whopping two previous cruises. I think I have more insight just from reading around this board and another one, plus a general travel board I've been a member of for several years. But it definitely makes a difference once you've been on that first cruise because you can say to yourself: "Self, now you KNOW what everyone was talking about."
And no matter what everyone says about liking or hating this port or that one, until you experience it yourself, it's best to reserve judgment and just go for the experience. Once you've been, you'll know if you want to go back.
