Vero is my favorite DVC resort.
The only "negatives" I can think of might be the fact that the beach is a little "wild" (pretty sharp drop-off, rougher waves, riptides), the island blacks out at night (no exterior lights to protect the sea turtles), and the surrounding area is not developed the way many beach tourist-strips are.
Of course, those are some of the very things that make me love it even more!!!
Other positives would be:
The best CMs on the planet, great recreation activities, beautiful decor/design, ocean-views, room-service (with Mickey pancakes!), a short drive from WDW, great ear-round weather, varied dining options, natural beach setting, easy beach chair/rec. equipment rentals, ease of movement from pool to beach, natural beach-life (sea turtles, shells, etc.)
Sigh. I'm counting the days. Literally.
