The best decision Trisha and I ever made concerning travel decisions was to do whatever the other person wanted: I’ll see whatever you want, and you’ll see whatever I want. Done. I can only assume this saved multiple arguments.
When we went to Europe in 1999, we visited 5 cities in 12 days. It was aggressive. Our game plan was to see the ‘must see’ sites of each, checking off as many boxes as possible.
Agreeing to see what Trisha wanted was easy. The only time I honestly thought about not going was the botanical garden in Barcelona. I had no interest in that — I’m not a gardener. Not even a little. But I had made a deal, and I went. It was one of the most memorable parts of the trip. Perhaps due to my low expectations, or sheer lack of knowledge before hand, but that is something I never would have experienced under my own planning.
When you’re planning your trip, don’t limit your itinerary to only things everyone will like. Take the opportunity to explore the interests of your companions. You may just be surprised how much you enjoy it too.
