Both are great resorts and both are fairly laid back and relaxing destinations. If you just want a quick break tapped onto a WDW vacation I would opt for Vero as it is only a couple of hours drive. If I was visiting WDW from the North East I would use HH as a break on the way home and stop 3 or 4 days, breaking the journey.
Vero is warmer all year round and has a much longer season that you could consider beach weather, HH is a more self contained and vibrant resort. The beach IMHO is better at HH, but at Vero it is on your doorstep and you can easily switch between beach and main pool. HH has a great facility in the beach house and a great slide but IMHO Vero gets the vote for access to the beach.
I think Vero struggles to be considered a destination in it's own right , whereas HH could easily be used as a primary destination for a whole vacation.
Golf is definately better at HH
IMHO there is nothing to choose between the facilities of either resort, I would base my choice more on how it fits in with my other holiday plans.
