They didn't have people sitting on the ends; the sides of the jumbotron are too narrow to really watch the entire game.
Not sure about the replay board. I'm sure they'd show them. We had seats near the top at the end zone. I could see and hear everything. No problem following the puck unless it was behind that net. However it was always seconds a you really didn't miss much.
