I was up there a few years ago, and flew with Don and two others.
I flew with Alex Clark out of Homer, which was a blast. He took me to some really neat places. If anyone every takes a trip to AK and wants to take a scenic flight and get to do the flying (or get their float rating), I highly recommend the drive to Homer to fly with Alex. He has a nice little cabin you can stay in. It was an awesome flight, Homer is a nice place too.
Also flew with Hermann Ruess out of Lake Hood, who was a great instructor, but you better be ready to work your butt off getting everything perfect if you go up with him, and it's strictly instruction only, no scenic flights with Hermann. But never the less a great instructor, I enjoyed flying with him.
Last flight was with Don Lee out of Talkeetna. If you fly with Don you can take a flight around Mount McKinley where you get to do the flying (or you can get your float rating), which was great. After our flight around the mountain we did some fun low level exercisers as well as float stuff. It was a really fun flight, but a little more pricey than the others.
I think I enjoyed flying the Cub in Homer with Alex the most. There is nothing better than flying around with the door open, in a cub, in AK, in the Summer. But you can't go wrong with any of the above people.
