I can't vouch for this particular tour operator. But I'm impressed with the variety of adventure trips they offer all over the world. It's worth taking a look and weighing them as an option. Especially of you are single and looking. Or single and looking for a vacation fling.
I like the fact that they offer a fair number of camping options. Those are great for saving money, although I know a lot of you like your luxuries. But these are not cheap trips so you may be a convert to camping for the sheer economics.
Be aware that if you want a private room on some of these trips, you might still pay a single supplement. But the organization does offer roommate matching if you're willing to bunk with a stranger. I've done that many a time. Let me clarify. I've bunked with a roommate of the same sex.
I can't say I love sharing a room. I like my privacy as much as the next guy. But the match up was never a disaster and I got to go on some pretty amazing vacations, for less money, by willing to make that compromise.
