You are right, travelling alone you got a lot of opportunity to meet different people. You will not be pressured to follow your schedules because you have no one to share your plans. You can do on the fly as per your schedules allowed. Most of my experiences travelling alone is due to my work in oil and gas industry. I have been assigned to many places and projects being on these projects i got to take a side trip going to landmarks and tourists destinations on the countries/places where I was assigned. You think its boring to go alone but I got the best experience doing it as I meet a lot of people and new friends, eat exotic foods, and experience the culture of the place.
