Calling residence was incredibly costly throughout my first solo trip. I put my Eurail move to good use and ended up visiting about 20 countries throughout my first solo journey. That gave me enough time to see the principle websites and exit one night. If I was actually enjoying a metropolis, I’d stay 4-5 nights. Travel time between cities was always less than a day. I knew I needed to travel after high school but I didn’t know the place to go or how to go about it.
