Who is this couple? And how can I reunited them with their vacation pictures?

Early this morning, probably around 6:15 a.m., we found a small case in the Kaneohe-bound lane of Kamehameha Highway just past the Kaaawa Fire Station. Inside, a small point and shoot camera, two extra memory cards. Unfortunately, no identifying information.

In the camera, vacation photos from a trip between Oct 22 and late afternoon yesterday, October 28. It looks like they were staying in Waikiki, but spent a lot of time on our side of the island, from Waimanalo to the North Shore.

Late Monday afternoon, they visited Temple Valley, then apparently met a friend in a bar, shown here.

In a quick scan through the photographs, I couldn’t see any clear, identifying items to narrow the search.

So I’m looking for suggestions of how to reunited these folks with their camera and their photos? All suggestions welcome!
