7 day Cruises Sat to Sat, Sun to Sun?

[sainter]

We went on our first cruise ever on the Magic a couple of weeks ago. Our western Caribbean cruise was Sun to Sun. While onboard, we booked another for next year on the Fantasy. I did not realize until a few minutes ago that this one is Sat to Sat. It makes sense because we didn't see any other Disney ship in port on departure or arrival day. And maybe I am the only one not to have realized this, but just pointing out to others... for us it means everyone needs to take an extra day off of work. Though so far, no one is complaining
