I prefer to buy the cheap ones folded nice and bring a couple. We have used the heavy duty ones but find it hard to find a place to dry them off. Pack a few cheap ones(dollar store, two pack), throw them away when done, and bring some extra if needed! I'm starting to stock up for our trip in March, I just store them in the front zipper part of the suitcase and if the weather states it might rain I carry them in my backpack!
