For example, a guest may be vegetarian, they may request special non-allergenic bedding or maybe you booked a table for them at a local hostelry.
It works like this:
When you want to create a "check-in alert" click on the guest name and on the Guest Detail box of the Guest screen click the new "Check-In Alert" button, as shown below.
You will then see the "Check-In Alert" screen where you can add the text of your choice and press the "Create Alert" button.
When this guests arrival day approaches and their details appear on the "Today" screen you will see the check-in alert below their details, in green. It will appear in both the "Checking In today" and "Checking In Tomorrow" box so you will have at least 24 hours notice of any alerts you have created.
A record of all check-in alerts is recorded in the system audit trail and can be seen in both the Audit Report function and the audit trail on the guest screen, shown below.
Any one booking can have up to 10 alerts added.
