Probably the biggest factor is the time of year you are going. If it is Spring or Fall that is great for both. Winter-Vero. Summer, I think I would pick Vero because I would rather be right on the ocean in summer. Additionally, how I am getting to the resort is a factor-driving or flying? Airfare to Fla. from NY is alot less than to HH or Savannah. If driving, HH is closer.
I would say it also depends on how you style your vacation. For example, do you stock up on food and eat in. If not keep in mind as previously posted, HH does not have alot of on sight food options. The food at Signals and the other one-forget the name, is very good, for quick snack stand type of things. The Shelter Cove area has several restaurants you can even get to go, whcih I did and rode my bike back to the
DVC resort. The Piggly-Wiggly and Publix are also convenient.
HH is great for kids -lots of activities and my kids 7, 9 and 10 loved having bikes to ride all over the resort and over to the beach house. I love the ocean, but did not mind having to go over to the beach house via bike, car or shuttle. We went min-golfing down the road a bit and did some island self-guided tours to the lighthouse. We love HH-the kids keep asking to go back.
That said, we also love Vero. There are a couple of very good in house restaurants, but we didn't venture out to anything else around Vero. When we go to Vero, we stay at the resort-that's it. Alot of pool and mini-golf right on property, walk on the beach. At HH we tend to do a little more-more active w/ bikes and such. Love them both-I couldn't choose.
Both very relaxing but our stays at HH have been longer-a trip in itself. Our Vero stays have been 1 or 2 days, after the
DCL ship, or drive up while visiting my mom in West Plam Bch.
Not sure if this helped, but have a great trip.
