@dconklin I think you'll be better served using a dedicated Kiosk app versus Safari in a single app mode configuration. Moki Kiosk is one to try if you don't have a large amount of devices in this configuration as you'll need to pony up for remote management. To get Safari in a kiosk like setup you'll have to resort to a webclip to get rid of the nav bar and other UI elements. Otherwise just running Safari in single app mode won't be much of a kiosk experience unless that's what you're after.
Or stick to nightly resets and use Return to Service to automate the process a little more.
