We are Dvc owners at Vero beach, and have generally had a few days there every trip (7 visits to vero) this year we aren't visiting because we find august just a little too hot to sit around the pool and now the kids ( young adults actually!) are older the activities don't have the same attraction for them.
There is loads of organised activities for youngsters - crafts, pool activities, 'parties'
And plenty of things to do in the resort - crazy golf, table tennis, board games, bikes etc,etc.
The pool has a counter service food - fries, salads, hot dogs, chicken strips etc and also serves the usual ice cream offerings and cocktails! You can also purchase refillable mugs for length of stay which is great when sitting round the pool.
The beach is a very short walk (20meters?) from the pool and hotel and it is great to have a splash in the sea - there are various beach items for hire - loungers/umbrellas, body boards, wave rider.
There is less to do in the evenings at Vero but they do have camp fires certain nights, movie nights and dvd rentals.
The cabin room is a bar which serves some snacks and has an outside veranda overlooking the sea (and thunderstorms if you are lucky

), there is live music some nights which tends to be easy listening background stuff and kids are allowed in here.
I would thoroughly recommend Vero for families with children aged 3-15 for a more relaxed few days, it is more like your traditional Pool/beach style resort, complete with the early bird towels on loungers crowd (Brits I think).
