Thanks Meitra, I am planning on doing cenotes with Del Sol but I'll have to confirm my dates before contacting them. I really like the idea of a waterfall too, and did some research online. There is a cascada agua azul....(blue water waterfall)...but I have no idea how far that is from Playa del Secreto where I plan on staying and if it's ok to jump in the water for photos. Anyone have any info? Thanks!
