I am planning a trip to Hawaii for August. Rather than fly non-stop from HNL to PHX, I thought that I would pop over to LIH on my way back. The fare is the same ($125), and it would give me a chance for an inter-island flight.

Also, I would have nearly 3 1/2 hours on a new island.

Any suggestions for what I could do during such a quick stop? I looked at Google maps, and it appears that there's a small town just outside the airport.

Also, when do I need to get back to LIH to get through security? Does US have a priority security line?

Thanks in advance.
