It would be convenient to have a daily list of visitors and mark everyone who came. What is the best way to do this?

Open the Today's visits table. This table is already filtered to hide reservations for customers who have already visited.

Click the reservation status button to record the customer's arrival and departure. The status will change from "Pending" to "Checked in" on the first click, and to "Checked out" on the second click. Once you set the status to "Checked out", the row will automatically disappear due to the filter.
