I can't believe no one's stepped up to loan this guy a board yet! If you were coming closer to where I am and I was gonna be around, I'd loan you one for 1) the good karma and 2) the hope that you'll return the karma if I ever come to Hawaii!
you can UPS a board under 6'6" within the continental US and the cost 'should' be around $60, but you never know as the rates seem to fluctuate quite a bit.
i just went to california for a few days and only found one shop that rents short boards. $30 for two hours. yikes.
here at natural art on hatteras island we have short boards for rent for people in your situation for $50 a week. we keep them in a separate place from our other rentals.
