Step 1 :Given that there are n benches and each bench can have a maximum of 2 people sitting on it, the total number of people sitting on the benches is \(2n\).
Step 2 :There are 8 people walking in the park.
Step 3 :The total number of people in the park is the sum of people sitting on the benches and people walking.
Step 4 :\(\boxed{2n + 8}\) represents the total number of people in the park at this time.
