Rolling Availability is a way for you to automate opening availability in HoppingIn. That is, instead of manually opening spots in rooms that have consistent availability, you can set HoppingIn to automatically open spots. Still, this happens only on a two week rolling basis.
For example, if your room has capacity for 10 children, but only 8 are currently enrolled, you can open 2 rolling availability spots. This will allow parents to book these spots, without you having to manually open them. To clarify, these spots won't automatically book unless a child that requests the spot has been approved to automatically book. Additionally, in the example above, once the two spots on a particular day are fulfilled, you would need to manually open additional spots for additional children.
This setting can be found in the editing view of the Rooms page.
