The others are right. The online check-in is what you need to do for cruise documents. It is very easy to do - so I highly encourage it.
My wife and kids did our first cruise just last month on Enchantment - and we had a blast. It really is a beautiful boat, and we got fantastic service from the wait staff in the My Fair Lady Dining Room. If you get "Baha" (from Turkey) as your headwaiter, Ricardo (from Phillipines) as your waiter, or Maria (from Poland) as your assistant waiter, then you will have the time of your life.
The Windjammer has a great view - but I was not a huge fan of the set-up. As I understand it, it is a new configuration. Basically the main serving stations are all in the middle of the room with no defined start or end points - so the result is, you get a bunch of people all pushing around going in different directions. It is a minor point, but is a bit of pain during high traffic eating times - especially days at sea. We came to prefer the afternoon snack (around 3 p.m.) as it was far less crowded.
Enjoy! We did!
