Vacation is a useful option for intermediate learners who want natural English without jumping into something too difficult. Learners should find many familiar words and expressions, especially when the scene gives enough context. Also, jokes, quick reactions and casual exchanges are a regular part of the dialogue. The story gives enough context to follow what is happening easily. Some conversations move quickly, so learners may need to listen to certain parts more than once at first. It should work best near B1/B2, especially for learners prepared to handle faster dialogue.
