Hello.
Usually (as you was suggested in your comment), such discount providing via coupon codes in Booking Calendar Business Large version: http://wpbookingcalendar.com/overview/#coupons
In your Booking Calendar Business Medium version possible to have some selectbox or checkbox in your booking form, and then configure additional cost for selected option at the Booking > Resources > Advanced cost page as 50% from total booking cost. Please check more about this functionality here: http://wpbookingcalendar.com/overview/#additional-cost
Kind Regards.

I have found the solution, thanks to your help. Working perfectly.
If you don’t mind, I’d ask one more question here instead of opening a new topic.
Is there a way in the booking form to have text field appear after a certain dropdown option is selected?
I’d like to collect tax info from customers that would like a receipt on a company. So I would first give a dropdown option, and if they select yes, 2 additional fields would appear to enter tax info.
Thank you
