I think I would just rent from TMM, I doubt there would be much difference in condition of their Kayak and other rental companies Kayaks. You might consider an SUP or two instead of the Kayak. S/V Mardi Gras has a set of SUP/kayak storage brackets mounted which can hold two SUP or one Kayak just outside the lifelines. We found the kayaks to be heavy and often didn't launch it because of the weight. The Sup is much lighter and easy to launch.

Cheers,
