Aulani I could see keeping it open because they are on an island so far away from the U.S.--part exposure risk is probably lower (Hawaii the island chain itself does have cases though in low numbers and all are travel related at this point) but also logistically harder.
I could see barring incoming reservations but given that if you close the resort many of the guests would be left out in the cold as flights are probably harder to come by they may be slower to want to close that...at the moment that is.
