Yes, we came back from Sicily and rapidly got on another airplane (or 3), flew another 18 hours or so, and another 6 time zones. We have already been snorkeling at the fabulous Kahaluu beach, where a turtle heading for shallower water bumped his rather sharp shell into my shin -- no damage. The fish and coral were vividly colorful, and visibility was great when we got there a bit before 7 AM. By 10:30 we left: the parking lot was almost full and people were beginning to kick up the sand underwater. Jet lag: it can be your friend.
