Forgot the name of a movie.
What is the name of the movie (recent, within the last 10-15 years maybe?) with the following plot: Family joins other families at cabins in the Poconos, or maybe the Catskills, in the 1960's - Husband commutes from vacation campground to work in city each week, while bored wife & kids & relatives are left at campground. There is a hippie man in a van who comes to campgrounds to sell the campers clothing. Wife has fling with hippie man, goes to concert (Woodstock?) with him, then leaves him & returns home to her family & her husband... Movie has some big name stars in it. Just can't remember names of stars, & especially can't remember the name of the movie - Can anyone help me with the name of this movie, please?
