For much of the island I would guess electricity might well be a problem 7 weeks from now. Perhaps it has a generator but that will require a lot of fuel a I don't know what the contract says about cancellations but I love that island, own property there and would not suggest anyone vacation then based on what I know now. Here we are better than a week after and the streets look a lot the same ..basic food and water is in short supply along with everything else, there quite possibly will not be a single restaurant open by first of November. Have you been able to talk with the owner or agen you booked through and know condition of house?
