FWIW....I'm booked for later next week....But I received this from someone who is close to management. Vero is supposedly prepping for evacuation as long as Dorian stays on the current path.
We have backup ressies at WDW...Just in case.
Also,
DVC will TRY to advise if there's a resort closure. Because of spam etc, notification isn't guaranteed, but pay attention to DVC if you're planning on Vero within the next 10 days,
