Yup, I temporarily disabled it and life was good.

But I can understand how this would frustrate people, especially when they don't know how to disable it or aren't given the password.

What about WS2811s with a pushbutton to temporarily disable, or a pushbutton on one of the GPIO pins, with the switch in a central location?

The included dashboard with the pi-hole is incredibly easy to use, so I just have it bookmarked on all our browsers in case someone in my family needs to pause it or whitelist/blacklist a site. We barely ever have to touch it though, mostly just to update the blocklists occasionally.

I was thinking use-cases for house guests or very non-technical folks (what is a bookmark?).

Arcade button[0] mounted on the RPi that initiates the 5 minute pause script?

Yes!!!

Guest wifi network which doesn’t go through the pi?

Yes you can. But having non-technical people verbalize the need to whitelist a domain is incredibly painful.
