Great code. Is it also possible to have this code triggered when someone add's a new product to their cart? I have already a code that clear previous products from cart upon adding a new product to cart (since people will only do one booking at the time).

add_filter( 'woocommerce_add_cart_item_data', 'single_item_add_to_cart' ); function single_item_add_to_cart( $cart_single_item ) { global $woocommerce; $woocommerce->cart->empty_cart(); return $cart_single_item; }

Thanks for posting this. I didn't know about this filter for bookings. I wonder if the effect is the same as the regular woocommerce filters 'wc_session_expiring' and 'wc_session_expiration'. This is simpler.
