I haven't tried travelling alone, but I think its really fun coz you dont have to consider anyone else's feeling if they are hungry, tired, broke, etc.. The only person you're concerned about is yourself. I think its d same with shopping. If you're shopping alone, you dont have to listen to anybody else's opinion about the clothes you want to buy. What i really mean is that travelling alone allows you to have more freedom to do anything you like, anywhere or anytime you wish to do it.
