8、 plan to leave room for some spontaneity (自发性) on your trip. Herein lies the beauty of traveling alone: You are your own master, and while preparation is key, there is always room for a change.Important Info Prior to TakeoffOne of the hardest parts of traveling in general is coming up with a list of

Besides, youre on vacation, and have nowhere to be!Another benefit of traveling alone is the ability to explore mu
