One of the things I'm gonna be analyzing really closely on my current playthrough is "what are the actual actions Storm and P do on their Beach Trip before they wind up finding the Hotel?" Because we see them from P's perspective, and he doesn't realize when the ritual starts. By the time Storm tells him what's up, they've already gone to the seashore which is about the most liminal space there is, bathed, purified with salt cause it's the ocean, waited till dusk, and built a bonfire.
Interesting to see if I can actually identify the entire ritual as Storm intends it.
