I read it that the maximum that can meet, indoors or outdoors, is 6 regardless of where they live. I think the problem will be, for a hire boat for example, if the boat has been booked for 7 people from different households. If the pick up is this Saturday, someone will have to get off and go home on Monday! (Children under the age of 12 are excluded from the numbers.) Basically the rule is no more than 6.
