We just did the same last week. The trip out and back to Anegada requires more time so to see it all means renting a car/truck/jeep and you need to get your money's worth. Cow Wreck beach bar should be an all day thing anyway. JVD is too much fun to rush through, Soggy in the afternoon and the next day, then over to Foxy's. Less moving the boat and more relaxing.
