I think traveling alone is good for you as you learn to be independent. I have traveled alone many times and it is only when I travel with someone I realize how much I prefer it. No waiting around and doing things when you want to and not having to discuss or compromise. The few travel companions I have had, were on my travels as I traveled portions of the journey with them. When people are on the same page if it's a lot easier than people with different ideas. I once traveled with a party of about eight, it started out as three and then became bigger as more people heard about the trip. It was hard work, there were factions and groups split up and logistically it was a nightmare for a long weekend.
