I've traveled solo and had a great time. Once you let the guys know you're not there for that, they will be respectful. Most of them anyways. lol.

You may want to spend your time alone, but if you would like people to hang out I'd recommend going to one of the Webcasts that Rob does. You'll meet really fun people. I went to a webcast my first night on my solo trip and after that I had a bunch of friends to hang out with for my whole stay. So yeah, GO, and have FUN your way!! You seem like you have your wits about you so no worries

I'd also consider establishing a relationship with a trusted driver that can be your go-to person for getting around. And a cheap JA cell phone can be really handy as well.
