i went to 3 games in long island last year. sorry if this may screw up your group plan but anyone looking to go to a game here is better off getting them closer to the game...tickets go for way under face value, in fact i was given tickets last year for free at the game outside. it should be even worse this year since the isles will likely be the worst team in the east.
craigslist, stubhub, ebay all will have tickets for around $10 or less and you can pretty much sit anywhere at the arena, whole sections were empty this year at the games i went to even on weekends. also, they have a version of student rush at each game that you can get $10 tickets with a student ID.
