recommendations for first trip to lambeau?

I searched the archives. thought there had been some threads by Tooner to guide first-timers, but didn't find anything.

Took the kids to GB in the 90's and we saw the Hall of fame, but this will be our first game.

Just looking for recommendations for you long-timers.

I know we want to be there early to soak up the atmosphere and to be sure to be able to rent seatbacks. I'm sure there are lots of ideas on how to best take it in, when to arrive, what to do while waiting for the departing traffic to lighten up, etc.

One particular question--I read something about WiFi coming to Lambeau, but wasn't clear if it's there this year or will be there next year.

Also, if you have recommendations for the best food choices in either the Atrium or the concession stands, I welcome them.

Thanks, all!
