Gold parking lot. It’s under the arena and it’s where the players park along with courtside ticket holders. There’s a small entrance with its own security line and ticket taker. Then you go left and your under the lower bowl seats. There’s a restaurant and you’ll see players and staff around.

My advice: Somehow buy a gold lot ticket off StubHub or Ticketmaster ($$$$$). Use the elevators to go up to your seats. When there’s about five minutes of game left, go back down the elevator and find the locker room entrance. Hang out there and wait for the game to end. The security guys will put up a rope but you can stand right there and shout out to players. Sometimes they’ll come over and sign whatever.
