Alaska Fly-in Float Fishing Trip Planning/Advice

[Toneloc]

Have only been to AK once for a vacation with the wife, but was able to get 3 days at a fly in lodge on that trip in 2023. Rivaled best fishing experience of my life and been dying to get back to AK for a dedicated fishing trip since. My 16 yr old son has really taken to flying fishing/ tying this summer. I am also lucky to have an awesome father-law who is getting into his upper 60s but still in awesome shape. Want to plan a DIY float trip for the (3) of us for August 2027 while son still can get away for summer and before FIL gets any older. Has any done a trip like this with (3) in a raft? Any feedback? I imagine it might be close quarters, but planning to pick a less technical river with relatively shorter distance, intending to fish more and raft less. The other option is find a 4th person and do (2) boats, but struggling on a good candidate for that.

Have been researching rivers, flies, timing, operators etc. Figured probably have quite a few AK veterans on this board. What have you learned from your past fishing float trips that you wish you knew before hand? Would be great to get some lessons learned.

Thanks ahead.
