If you're not planning a deep dive into the local culture, this trip is good, but you won't spend more than an hour at almost any location. On the last day in St Andrews, you only have two hours for lunch and some walking. Personally, I don't like such a rushed itinerary. Having a specific focus each day for two hours would be more sufficient. Don't have too high expectations for the weather; it's usually unpredictable. However, the Highlands are very beautiful and worth visiting.
