AWWW !! Every detail of your trip sounds MAGIC !!
May I suggest - if you wish so - to visit the BEAUTIFUL and GENUINE Germaine's LUAU ?
Here you can see their official site : we thought that , in spite of what some people write on Tripadvisor, this was one of the best luaus we happend to enjoy during our visits to Hawaii ... and
IT IS VERY CLOSE TO AULANI !!

IMU Ceremony (when the pork is undigged from an underground oven)
And moved to the buffet
Part of my dinner : food was well prepared and presented ! ( Of course it's buffet fare...)
During this luau dances and "performers" were really "old Hawai'ian stuff" !
Just a thought ...
