I stayed at the Sheraton decades ago but I will answer assuming it is still a typical Sheraton Hotel.The beaches for the hotels is one long strip of sand separating the ocean from the beginning of the hotel property. That sand connects pretty much all of the hotels as a sidewalk does. I've never noticed a difference in the sand area (that we are considering to be the beach). It is where everyone walks including people who are not staying at any of the hotels on Wikiki. You never know who is going by. As I mentioned in the review, theHalekulani pool attendant advised me not to leave my things on the beach. At the Halekulani there is a gate separating their pool from the beach which is not the case at the Sheraton, though the Sheraton did have a person watching to see if their were people coming from the beach who obviously did not belong at their pool.The beaches as far as I could tell are the same, the pools are as different these 2 hotels are in general. The orchid at the bottom of the pool at the Halekulani Hotel is stunning. It's quieter and like all upscale hotels they have more security which would be a plus with children. The Sheraton is a busy pool with no separation from the beach. I'm not sure who's authority it is supervise the beaches but they are usually pretty busy. I'd be happy to answer any further questions.

Thank you for considering Halekulani for your celebration visit to Oahu. These rooms have either a King Bed or Two Twins. We do have the ability to convert the twins into a king with a kit as you described. If you call our Reservations team at 800-367-2343 they maybe able to better assist you with the King Bed. Thank you
