Kinda expensive to rent a POD in your case wasn't it Don? Not like the POD drivers could just drive your POD from the mainland over there to Hawaii, right? 
In all seriousness, I agree that a POD is a good alternate. However, you do have to be sure to pack your stuff carefully, as in that situation the overall responsibility of the items arriving intact will be almost entirely on you and not a moving company.
