If you need to get in touch with your Guests you may send them a message using Diwerent messaging system.
You may also try using different forms of communication such as telephone or e-mail. You can find your Guest's contact number and e-mail in the Bookings section of your Personal Account by clicking on the relevant booking.
Keep in mind that many Guests don’t have access to their phones or have an alternate phone number while traveling, or they may also be in-transit or encountering travel problems, so we suggest that you try combining different forms of communication to reach your Guest.
