Just off the April 12th (8 nights)sailing of C. Liberty. Went with another couple from a different city.
Embarkation - no problem, fill out your paperwork in advance on the net, you're good to go. Expect lines, but they move rather quickly.
Cabin - we had balcony cabins on Deck 6, near the midship elevators. Great location, close to everything - since this ship is soooooo large, a central location makes it a bit easier to get where you want to go.
