Karen and Donald and their 6 children are a party of 1+1+6 = <<1+1+6=8>>8 people
Tom and Evan and their 4 children are a party of 1+1+4 = 6 people
All total, there are 8 + 6 = <<8+6=14>>14 people at the beach house
There are 16 legs in the pool and everyone has 2 legs so there are 16/2 = <<16/2=8>>8 people in the pool
There are 14 people total at the beach house and 8 people are in the pool so 14-8 = <<14-8=6>>6 people are not in the pool
