Display total price for guest.

dont know if this will help you but maybe you can try this steps:

1. On Settings > Booking Options > Customize Feedback Messages > Successful booking, I added this placeholder “Booking successful. #_BOOKINGTICKETPRICE”

2. On your theme functions.php add

function my_special_function($value){
	global $EM_Booking;
	if( is_object($EM_Booking) ){
		return $EM_Booking->output($value);
	}
	return $value;
}
add_filter('option_dbem_booking_feedback','my_special_function');
add_filter('option_dbem_booking_feedback_pending','my_special_function');
