As a guy who just came off a luxury honeymoon, DO NOT leave your room upgrade to chance. You only do this once in your life, and you don't want to have the added stress of hoping you get the room you want when you arrive. I promise you, you will not notice the extra $1000 you spend for the perfect room, but you will cherish the memories of that perfect room for a long time.
