The success of my hammock-swinging experience here is yet another way in which Palenque has surprised me. I thought that hammock-swinging on Tulum beach would be the easy practice run, in preparation for the anticipated "grand challenge" of Palenque. But actually, it's been easier and more enjoyable here than in Tulum.
Today I finally did what I've been meaning to do ever since I got to Tulum: I moved to the beach, and set up my hammock for sleeping in. I'm staying at a cabaña lodge called Mar Caribe; they also rent out hammock space for 50 pesos a night. This is the way to stay in Tulum.
