I love Vero Beach and have been there many times. In fact, I'm going back in June. But, this is not a resort with a lot of attractions or activities around it. It's the kind of place where you really need to make an effort to find much of anything else to do outside of the resort. Will you be there for a whole week? If not, I bet you will find plenty to do at the resort. You can rent bikes from the resort and do a bike ride. There is a mall not too far from the Disney resort. There is also a downtown area of sorts in Vero Beach, but I have neve been there. I get the impression the downtown area (if that is even what it is called) is small, but that is where the other timeshare resorts are near.
Vero beach is a very fun resort with lots to do. Lots of activities and movie nights and stuff like that. One thing to be prepared for is a very warm pool. Honestly, the pool gets so hot in July, it is far from refreshing. They need another pool complex at Vero. The waterslide is a blast -- very fast.
We like Vero Beach and Myrtle Beach but they couldn't be more different. Myrtle Beach has so much going on you can't trip without finding something to do. Vero Beach is the complete opposite and you can go miles and miles before finding anything more than a house or a small store.
Now, if you drive further down I-95 to the West Palm Beach area, you will find lots do do. You can probably drive north and find even more to do.
If I am remembering right, there is a small (kind of plain) off-site minature golf place not very far from the resort. I had two teen cousins with me on one of my trips and I was really stretching to find things to do at night with them and we discovered an off-site minature golf place. Other than a mall, there wasn't much else to do.
