We're going to take a chance on the construction. I called the Halekulani, and talked to a very helpful person, who didn't try to pretend that noise doesn't exist. She agreed that there's a difference in various wings, and we got a reservation in the Makai wing, perpendicular to the waterfront. I expected the kind of bland, "Oh, all of our rooms are very quiet."

Thanks for the pointers, and I'll post a report after we get back.
