I don't know why most of my friends prefer to travel in the summer, but I love it when I go in the cold seasons, then it's a unique atmosphere that not everyone can feel and appreciate. Not long ago, I found this site
https://yourtravelitinerary.com/plan-itinerary from which I learned a lot of exciting things you can do in a winter vacation. And when I showed it to my friends, they decided to try it with me this year. So after we return, I'll tell you if we lured them to travel in the winter or not.
