We are sailing on April 2, 2023 for 19 days from Lisbon to Miami on the Norwegian Sun. We received 600 internet minutes (300 each) as part of our booking, but this will be a working vacation for me, and I will probably plow through those in a few days. I don't want to upgrade before we leave because I want to use my OBC to offset the cost. Does anybody know how much it will cost to upgrade to unlimited once we are onboard? And what if we want to use up our 600 minutes first, and upgrade several days into the cruise?
