ResBook never sends any booked room information to Cronofy. It only sends the `Booking Number - Booking Name` as summary, Arrival & Departure dates and status, guest name, total amount, important note, and comments in Description and event location data which is the address of the room.

There is no way to send the room names against the bookings to Cronofy. The only workaround that can be done is to add the room name in the 'Booking Name' field in the booking form.
