I don’t know why I wasn’t smart enough to even think of this.If you're not able to get a microwave in your room, there are microwaves at Ulu Cafe for anyone to use.
The Poly has a microwaves in the food court area. I found it was simply too far to walk from the room just to microwave a hot dog.
Perhaps Aulani is more compact than the Poly to make this more useful.
