Can't specifically answer your question, but the nearest Whole Foods is at a mall, the exact opposite direction from the airport as is Aulani.
WF is east of Diamond Head at the end of the H1 freeway.
Aulani is past the west end of H1 freeway.
The airport is somewhere in the middle.
It would add a lot of drive time on the trip from the airport.
eta: according to mapquest, the airport to Aulani is about 22 miles(32 minutes depending on traffic)
airport to whole foods to Aulani is about 41 miles (62 minutes depending on traffic)
I guess it's not as bad as I thought it would be, but drive time can vary drastically depending on traffic and time of day. 62 minutes would be best case scenario.
Also, there is another whole foods in Kailua. It's further away, and would add about another 11 miles and 15 minutes to the trip.
