Never done the SP. Done the Nat Seashore numerous times. Did one of the high demand beach side loops once. OK if you like the beach, don't mind the sand if it is windy & don't mind the wind. Bermuda is our home so East Coast beaches don't impress us much. We like the bay side. Chance of getting some shade, shelter from the wind, no blowing sand, think the horses favour the bayside too. Have had them poking around the site everytime we have been there.
