The NFL rents out the entire JW Marriott at Ko'Olina for players, coaches, family and whomever else is attached to the NFL for the game. By doing this, they actually cordon off all of the hotel to the public and have high security. I learned that first hand last year when I went there with my 3 year old son to walk around the outdoor aquarium at the hotel. My son likes seeing the stingrays and sharks. We were stopped and not allowed on the hotel property b/c we did not have any NFL credentials. My son actually started to cry and was asking me why they didn't like us.
The security guard did give me a little tidbit of advice. He said that you can get into the hotel if you have reservations to eat at one of their restauraunts. So, I made reservations for lunch on one of those days and we went in there and security verified we had reservations and they let us in. We walked around and saw a ton of NFL players and coaches. We even hung out at the poolside bar for 5 minutes and we were about 5 feet away from Peyton Manning. I got the feeling that security wouldn't tolerate asking them for pictures or autographs so I didn't really try.
