When we went on our cruise, we bought one of the minute bundles for their wifi. I don't remember exactly how much it was, but of course it was expensive. They track you from the time you "log in" until you "log out," whether you're actually using any data or not. What I did was compose my emails while not connected, then all I had to use was maybe 5 minutes to connect, send email, download email, and then log out and read email. You have to be real careful, kinda like in the olden days of AOL and dial-up where you paid by the minute! And it was painfully slow, I don't think any sort of video chat would work very well.
