Halloween at an AirBnB

What, pray tell, is a guest supposed to do?

Go out and buy candy?

Request that the host provide candy?

Scrounge around for something to distribute? Something a previous guest left behind, like maybe an overripe clementine or a handful of Kikkoman packets?

Or will one have no choice but to commit that ultimate act of Halloween misanthropy — the switching off of the lights?

There is no roadmap here.
