I personally think that you have made the right choice so far but I also believe that you should at least experience the rest of the islands geography. There are lots of interesting nooks and crannies. Just drive right to the ocean and then take a left and repeat It would be really hard to get lost if you have a few hours on your hands. I also suspect that once you have dealt with the crowds and the traffic on the Dutch side one time you will know what to do next time.
