Just returned from Aulani last week and had this same question before our trip. We are WDW Annual pass Gold holders, which entitles us to all the free photo passes. The bands definitely do not work at Aulani, however once you get the PhotoPass cards from them, just go into your My Disney Experience account and manually enter the Photo Pass numbers where directed. I did just that on my phone while there and they all came up. I was a bit worried I wouldn't be able to download them from my computer so bought the CD anyway but when I got home they were all in My Disney Exp acct and able to download.
