You need to play at the casino with your seapass card in the slots or give to the game host for table games. Anyone who plays at least a dollar will become CHOICE and then after the 2500 point is met you become PRIME.
I am doing a B2B on Nav in Sept that is a casino comp. I brought Zoom for the first 5N cruise but the 3N cruise I will use my D internet and Prime internet discount.
