Two of us were scheduled to fly from SIQ to VQS and return in December, 2017 at a cost of $300. As I explained to VAL via email a few days ago, we said "We do not believe that it would be proper to try to enjoy a vacation there while the citizens are suffering so much including little power & drinking water."
VAL's response was absolutely no refunds (as stated in their reservation form). I would have thought there would be some leniency with the hurricane damage but apparently not.
VAL did give us equal credit to be used by August, 2018 so IF Vieques & PR has recovered enough by then PERHAPS we will try to go again.
