I've only actually been to REI once in Dallas. We don't have one here in FW. I just found the trip online. If you go to their website it's under Adventures. Of course this being my first trip I can't recommend it! HA! Not many reviews out there either..couple bad (schedule changes) and a handful of good. I had to wait to book my flight until enough people registered. Their domestic stuff seems priced well compared to other guided trips I looked at. I'll report back when I return.
