I just got back from HH yesterday. The beach is big, clean, no rocks, and very broad, especially at low tide. There was no riptide to speak of. There care many shells at the water's edge, and the biking on the beach was fabulous. We also enjoyed flying kites on the beach.
We really loved it. I actually appreciated that the main resort was not on the beach, because my kids had much more variety in the way we spent our days. The main resort is 1.3 mi from the beach and is really beautiful!
Good luck!
