Since we use object labels to store bookings, if you change the label of a booked object, that object (e.g. a seat or a booth) will appear to be available again.
For example, let's say seat "B-24" has been booked. If you rename row "B" to "C", the seat will be available again for buyers. Same thing if you change the seat number "24" to "48".
Therefore, if you need to modify a seating plan for which tickets have already been sold, please contact us at email@example.com before making any changes!
