I recommend Burning Man as a dry run. :->

There are no stores for forgotten supplies, you have only what you bring with you. Run out of water? Oops. Want something to sleep in? Bring it. Want food? Bring it. They do provide portapotties and a central shade/"cafe" where you can buy coffee and tea, and you can buy ice. That's it.

It's the perfect bug-out/shelter-in-place test.
