Without your dates of arrival and departure, it is impossible to accurately answer your question. For each Sunday, Monday, Tuesday, Wednesday and Thursday night that you stay you would need 30 points, Fridays and Saturdays would need 60 points each.
"Offical" Accomidation is 8 people, and it is supplies for eight with glasses, utensils, flatware, etc. Unoffically, 9 people have been regularily allowed, but you need to provide sleeping accomidations on your own, unless # 9 is an infant, because pack n plays are provided.
Hope this helps!
