It's like 400 pesos for a ceremony there and it's in buggy hell bonfil, I'm a little biased but i hate being itchy and most of the year they feast on me there. I really like the one at that park it's only drawback being it's by the creepy pyramid. I'll try it though. I personally don't consider psychadelic experiences even ones like aya or mescalin to be "spiritual" necessarily, I personally see them from a therapeutic almost scientific point of view, the ceremonies even the tame ones are a bit much for what I want out of those experiences.
