Go to Reservations > Manage Reservations and locate the booking using the date filters or search box at the top of the screen.
Next, click the "+" icon to the left of the reservation number to expand it and see the individual RESX numbers (room reservations).
In the "Guests" column, click on the drop-down arrow and enter the guest's name. As you start typing, HOP will suggest possible matches from your CRM database - if the correct person appears, click on their name to select them. If not, finish typing the name and then press the "+" icon to add them to your CRM and also save them onto the reservation.
Alternatively, click on the RESX number, or select Edit Item from the drop-down menu next to the RESX number, and enter the guest name on the "Detail" screen.
