Ok, well people need to invest in and learn iOS just like any other operating system.
Well, for me, expecting people to look in Accessibility settings for guest features isn't user friendly at all. I have hearing, vision, and mobility problems, so I'm always poking away through the Accessibility settings, but I don't think it's fair for people looking for guest mode to have to look under Accessibility -- after all, guest mode has nothing to do with accessibility in most people's minds.
