Good advice on going " solo"
I'd start with a short trip that allows you to bail out, IF the experience isn't what you expected or wanted.

I'd also remember to think twice before acting.
Unlike a group trip, your on your own for better or worse.
A momentary lapse in common sense/caution can get you in trouble fast.

I always ask myself " What's the worst that can happen?"
And more important, what can/will I do if it happens ;)
Staying in the moment will go a long ways toward staying safe and enjoying your experience.
