When we went to Aulani, four years ago, we purchased DVC insurance, as we do for all of our trips annually. I was especially concerned since my elderly Mom was living at the time, that if we needed to return due to a covered reason, a medical condition for her, that we could get return quickly and our flight and remaining days of our points would be covered via the trip interruption clause for a covered medical reason.
Are you saying that DVC insurance is not issuing insurance for Aulani in general or are you saying that a volcano erupting is not a covered reason?
Flights are so $$$,
I would definitely purchase DVC insurance if you have the opportunity!
