Please help me find this family movie about a boy he went vacation with family

The movie is about the holidays. A boy goes on vacation with his brother and parents and his newly married aunt. On the way, in a scene, the boy takes off his mother’s shoes while sitting in a cart. The boy hates his aunt’s husband. In one scene the boy and aunt’s husband and daddy go hunting. In one scene, the uncle (aunts husband)and father shoot at the bathroom door and practice shooting while the maid is in the toilet. At the end of the film, the boy decides to stay there and even writes a farewell letter to his parents with a misspelling that, if I am not in mistaken, he mistyped the cave, but later regrets it and returns to the city with his family.
