I go every year this weekend and not a problem at all..seems Labor Day weekend is busier from the staff I talk to..Have heard good things about the Mirage sportsbook but EVERY Sportsbook is packed to the gills by 10 AM...Around 8:30 AM is probably the latest to find a seat of your choice and have not a long wait in line to place some bets..(info you probably know already,just thowing it there incase)
Orleans last year I got down there that early,got my fav seat at a VP bar,then joined a growing line of betters that snaked around.Bets in and back to the bar by 15 minutes till 10..
I try to put in some bets the day before,but something always comes up and I'm in line Pre-Kickoff...My fav day of the year!!
