The module handles messaging around a stay: reminders before arrival and customer self-service cancellation. Its settings have two tabs.
Cancellation settings:

- Cancellation cutoff (hours) — how many hours before the stay begins the customer loses the ability to cancel. The default is 24.
Reminder settings:

- Enable reminder emails — the master switch for reminders.
- Reminder 14 days before, Reminder 7 days before, Reminder 1 day before — which reminder points are active.
Reminders are sent by a cron job that runs once a day, so on a site with no traffic — where nothing triggers WP-Cron — they may never go out. Reminders that were sent appear in the reservation modal under REMINDERS SENT.
