When does Mexico Pavilion fit best in your EPCOT day?

Usually as a World Showcase break. It is an easy place to combine a gentle boat ride, Mexican food, shopping, and a break from the heat without spreading those plans across different parts of the park.

What is easiest to pair with Mexico Pavilion?

Nearby World Showcase stops are usually the easiest add-ons. Plans farther across EPCOT can still work, but they often bring more walking, more timing pressure, and a little more effort for the day.
