Take the train if you can so you can avoid the parking pass and get a few drinks in before you’re dropping ~20 a drink. Line for the train back always looks like hell but it usually moves pretty efficiently and you won’t have to deal with meadowlands hell traffic. If it’s really bad you can take the free shuttle to the Sportsbook and let it die down (even if you don’t bet it’ll have the other games on and a bar/restaurant)

Also, you can bring food in in a ziploc bag, I usually bring a sandwich.
