Hello,
The possibility to use the different coupon codes for getting the discount by visitors is available at the Business Large version.
You can configure the coupon code discounts at the Booking > Resources > Coupons page. Also you are need to insert the special coupon code shortcode into the booking form at the Booking > Settings > Fields page. Please test it at the live demo of that version here.
