Not in the slightest. It shows independence more then anything. Your able to decide what you want to do and go do it. I have travelled alone on a few different occasions and loved it. It was like a break from friends and family to a place no one knows me and i loved every minute of it.
Not at all! Travelling along means you get to do what YOU want to do and not have to follow someone else's agenda. I enjoy ALL travel, whether I'm with family or friends, or by myself. Be open to all possibilities and you'll have a fabulous time. Some of my best vacation memories are the things that happened when I ventured off by myself.
