I have never seen the gate locked. Even if it were there are people coming and going all the time, just follow them in. No problem getting to Papalua.We chose Marriott's Ko Olina over Aulani in March for the same reason I do have a question though. If we walk over to Aulani do we have the ability to go to Papalua Shave Ice? Or can you not get within the pool area without a key/wristband? Thanks!
