Games have always been a point of contention for us on the ship. We've had instances where we've started watching a game (opening day for baseball) which was advertised as playing in the Navigator, only to be kicked out halfway through because they were starting at DVC presentation. We've tried to watch games and told they needed to turn them off for overflow for the entertainment in the other room. We've had similar issues as above where we've been watching a game and had them turn it to another sporting event - it had to be the same game on all the screens.
I've made comments on this on the comment card for probably 4 of our 7 cruises, going back to 2003. It's obviously never going to change. We'll keep trying, but our expectation is that we won't get the games we want.
