For starters, my family really likes Vero Beach. Right off the bat I will say that you can find MUCH better beaches in Florida. It is not a miles long, half mile wide white sand beach. It is a beach, with sand. We have, however, swam many, many times and had much fun there. Swimming, wading, body surfing, jet-skied. Nice waves, warm water.
The resort is quite nice, I would say laid back. Very nice swimming pool with large slide. Good kiddy swim/play area. I would say the resort is relaxing, on the quiet side. NOT silent, but not spring breaky.
Not many ocean view rooms.
I guess it is hard to describe these things to others, since I am sure our tastes differ.
Our family definitely likes VBR. We often split our vacations between VBR and a WDW resort. Inevitably we end up saying we wish we had spent more time at Vero and less at WDW. And we like WDW very much.
I guess give it a try for yourself and see what you think.
