I'm using Woocommerce Bookings. I would like to use the person type as a service type. For instance the product is hair saloon service, the person type is long hair cat (price 1000, duration 120 mins) short hair cat (price 500, duration 60 mins), hair wash and dry (price 500, duration 30 mins) etc. The final price is calculated by WC Bookings. I would like to have the same logic for the custom duration fields to add them up and calculate the final duration at the check out. So the flow is that the end user chooses date and time for booking, chooses the person type for example short hair cut + hair wash and dry --> duration = 60 + 30 = 90 mins. So the booking of the block is stat time + 90. I can use either Woo Product Adds On or Custom Field.
