Gluten free & Dairy Free at WDW just did a podcast on eating gluten free at Aulani. Here is a link to the podcast on her website. http://gfdfwdw.podbean.com/e/episode-028-disneys-aulani-resort/
I haven't listened to it, so I have no idea if it is good news or not...but hoping it is good since we too would love to go in 2017.
Ate at Ama Ama last night at Aulani. One of the teens in our group has celiac. She had her own special menu, and they were very knowledgeable about what on the regular menu could and could not be adapted.
