Have you considered sitting under a small canopy or umbrella? I did that for a week at the beach, and it solved the glossy-screen problem quite well. Just make sure your back-light brightness is turned all the way up. Since rugged laptops that don't let dirt in easily can get very expensive, I wrapped mine tightly in a plastic bag on the way down to the beach, and while I was working, only exposed what I really needed. I kept the plastic wrapped around the outside, and over the edges as much as possible. Even so, I made sure I gave my keyboard a good vacuuming each night.
