I would call Vero's front desk, and see if someone can answer your question. If they cannot, they should be able to provide some contact for you who can. Wished I could answer your question. Good luck!
The beach is public property, so yes you can use it. I'd recommend using 'good form' and setting it up either side of where the resort rented chairs & umbrellas are thou.
Absolutely! I would not want to be in the way, just want a large enough shade space for us so the kids can get out of the sun as needed (there are 7 of us so that's why we were thinking of something a bit larger).
