I hunted with Renfros once, and I had a very mixed experience. I regret not going with Papa Bear as I have never heard a single negative thing about them.
Wade takes A LOT of unguided hunters (I think over 100 annually now), and your experience can be very dependent on the luck-of-the-draw where they drop you. There were guys while I was in Bethel who were extremely upset because Wade's assembly line of DIY hunters came to a halt when guys were not being flown out in good weather. We were delayed about three days before we were flown out, which I didn't think was that big of a deal. What concerned me the most was, the pilot who flew us had extremely poor judgement; he overloaded our plane and took three attempts to get us off the water in Bethel, then crashed the plane because it too was overloaded about 45 minutes after dropping us off. That video is on youtube, and thankfully all four people on board walked away, but Wade's company had three (3) airplane crashed that year.
We had other hunters very close to us (I could see a guy walking the shore of the same lake we were on, dropped by a Renfro plane). Our food package was a complete joke, and the gear package we rented was not maintained or taken care of. If you go with Renfro's, I would take your own food and gear.
Most find Wade to be a good guy, but he does have a history with the AK Fish and Game you can look up online. The good thing is that his area still has a very high population of moose with the majority of that having no antler restriction. For that reason, his success rates are high, but many are immature bulls in the 35-45" range. Of course, some guys are shooting 60"+ bulls, too, but the majority of those are taken by his guided clients. We were into bulls daily, but nothing over the mid 50's that we could find.
In all honesty, your attitude, perspective and perseverance will make or break your experience with most any DIY hunt.
