>>272734I've planned all my trips as solo adventures. I'm not very sociable to begin with, and I like the freedom of being able to push myself as hard as I want on a daily basis.
I did ride the last ~2000 miles of my last long trip with a 4 other people I met along the way. Having some company was kind of nice, and making nice meals for 5 people is much more time-efficient than making them for one, but I slowed down by a good 15 miles per day, spending hours upon hours hanging out with the other faster cyclist as we waited for the rest of the party to catch up. Granted, some of the waiting was in really nice spots, but a lot occurred in front of gas stations so he could buy snacks, while on my own I wouldn't spend any time sitting in front of one.
If you do go with someone else, just be sure that they'll be a good companion 24 hours a day, 7 days a week.
Independence and the flexibility which comes with it is another really great part about touring. In the right areas, you can start and stop exactly where you want, when you want, only tied to civilization by the road in front and the road behind.
One more bit of advice: look into the laws regarding camping where you'll be. In the US, stealth camping is legal, so long as you don't pass fences/no-trespassing signs and leave if someone tells you they don't want you on their property. If things don't work the same way where you're riding, another decent option is to just ask people if you can spend the night on their lawn. I actually met one guy who gave me dinner when I did this, and I spent another night in a basement of a couple whose daughter was out hiking the Appalachian trail.
