here are my thoughts:
The whole idea of leisure travel is to experience something different, no? If not, just stay where you are.
What people cook and eat is as important a cultural matter as anything.
Learning is growing.
All tastes have to be developed. If not, we would all still be delighted by Teletubbies well into adulthood. Nobody is born reading long books, going to the opera, ready for college, or climbing a mountain. Trying new foods and challenging the conditioning we have received leads to greater variety, excitement, and deliciousness in our lives for those that are open to it.
