Oooh, where you goin'?
Yeh airbnb is pretty chill! I hopped from host to host when I was traveling with my mum and I'm pretty sure people only turn you down if you sound like an axe murderer (or if they're busy). Udderwise they want that cash flow.
Unrelated to travel but related to RP, I think I've come up with a possible side/NPC-kinda character? her name would be Petrichor, and she'd be some sort of AEGIS teacher/tester/examiner/whatever works. She'd be pretty strong, a water-manipulator, but also a bleeding heart and crybaby. Like biblical flood crybaby. Probably why she's not on first string as far as active duty goes. But she'd be able to pull herself together if she really had to, say if the students were in trouble.
