With all due respect to the assertions, it is fair to ask whether the impact of local events is always as determinant as suggested, or if it is rather a circumstantial consideration.
For an imperative business trip, a specialized trade show can be the very reason for the trip, making the local event a motivator for the destination, not just a factor to evaluate.
The hierarchy of criteria is far from stable and depends heavily on the primary purpose of the trip.
A family trip for a wedding, for example, will make the importance of a local festival secondary, or even negligible, compared to the priority of family presence.
