to answer you question, yes you should be able to see it on the ship. They seem to carry the major networks on the satellite feed they use for the televisions. Worst case you have to watch when you get back, but you may be able to catch it on the ship if you want. Don't plan on watching on the internet service you get on the ship. You pay by the minute AND it is too slow to keep up with a video feed. You'll go nuts when it freezes up at the most important parts....
