Our 3 families had a blast in Duck Creek. The 3 levels had their own individual living/hangout areas so we never felt like we were in need of more space. The 7 kids took the upstairs (2 bedrooms, bunk beds w/ bonus mattress, futon, and full bath), one adult couple took the main floor (one bed with full bath ), and the other two couples took the third floor (2 bedrooms, one bath).
We loved watching the wildlife, fishing, and adventuring.
