This question is one of interest, but also may be one to test your geographical knowledge. The last thing you want to reply with a city and country that do not exist, for instance! Other than that, there indeed is no right or wrong answer to this question. Choose a unique destination that will make you a stand-out candidate. If you choose Paris, for the Eiffel Tower, you may not be memorable.
"I love to travel and have had many great opportunities in the past few years. If I could choose any destination for my next, I would pick to stay at the Icehotel in Jukkasjarvi, Sweden. It's so interesting to me that I could stay in a hotel carved entirely out of ice. Also, the town has historic buildings to explore, such as an old church dating back to approximately 1607."
"I have a bucket list, actually, and would love to tell you about it! A couple of years ago I made a list of the most fascinating UNESCO World Heritage sites and decided that I would choose one from North America, Central America, the Caribbean, South America, Africa, Asia, and Europe. So far, I have visited Leon Cathedral in Nicaragua, and Ephesus in Turkey. Next, I am planning for the Paleolithic Caves in Spain. It's important to me that I am well traveled and exposed to what our beautiful world has to offer."
