It is fairly easy in Theatre Manager to identify the accessible areas using colour, text, and/or an icon. We recommend changing the background area of the accessible seating to be blue (as per the image to the right) to clearly identify where they are in the venue.
You may also want to put a legend on the map for 'Price A', 'Price B' and 'ADA seats' so that it is equality and abundantly clear where each area is.
