Part of the fun of a spontaneous trip is going wherever the night may take you. While it is amazing to wake up some place and not know exactly how you got there, it is absolutely terrible when you get to some place amazing only to realize that you don’t know how you’re going to get back. Whether you familiarize yourself with the city’s public transit, plan on using Uber or Lyft, or throw up the bat signal to an acquaintance who lives near by, know how you’re going to get back to your crash pad—even if you’re lucky enough not to need a ride home until the next morning.
