We stayed in a standard "hotel" room our first trip to Aulani. The room we had seemed to be about the same size as the Beach Club rooms at WDW and most other "deluxe" Disney properties. I believe there are some rooms available with a king sized bed, but if it's anything like other Disney properties, there may not be very many of them available. We were there with two adults and two 11yos. The other times we have stayed in a one bed room villa and the bedroom had a king sized bed each time. I hope you find what you are looking for.
