We had a small portion of a very large family, there were 3 of our 11 total siblings, with some of the children and families that went with.
In total we had a 1yr old, 4-11 yr old's, 1-14yr old, 1-17yr old and 5 adults. The space was great for this group but we would have had to re think it if we had had even 1 more spouse. We all enjoyed that there were spaces other than just the bedrooms that the teens and kids could hang out together and separately. We could all sit down to dinner together and that especially was great.
The grounds outside were beautiful, we might have spent more time hanging out outside if it wasn't so hot, but since it was pretty hot being the end of July - Beginning of Aug, we did not feel like the kids were bored or "shut in" hanging out inside. We did have activities so the 11yr old's were not just playing video games inside but there are games and some things to do in the house for many ages as well.
