If you're looking at Disney's Vero Breach hotel, it's a great resort and top class service and facilities. You'll get a good amount of information from the DVC boards, you can also do a search on Disney's own website.
Vero Beach itself is a fairly quiet town, although there are a number of good restaurants in the town. There are some decent golf courses, a good nature reserve area plus a treasure museum ( there were many wrecks off the coast so this is quite a full exibit apparantly) and the beach area is pretty good, although as has been said in winter it can be a little chilly (being the Atlantic coast) and can get a little rough. The beach by DVC @Vero is , generally safe, (although as with anywhere around Florida you must be aware of beasties) but a couple of miles up the coast is one of the inlets to the "lagoon" area behind the islands that lie just off the Florida coast, because of the high number of "bait fish" that go in and out of these chanels it is a favourite spot for the larger preditor fish ( read sharks) to patrol. Don't take this to much to heart, almost anywhere around florida shores there are sharks, just be aware this is the case and swim accordingly.
