Jackson / Snake Drift guide?

All,
Well, finally convinced SWMBO she needs to see Yellowstone and the
Tetons before she drags my ass to live in New England.

Heading out for 9 days starting 4 Sept. Staying in Yellowstone for four
days at a cabin at Mammoth Hot Springs then off to Jackson. I can find
my way around Y-Stone fine and I¹m looking forward to revisiting Slough
Creek, heck, if I have time maybe a trip up to Fawn I'd like to take
her on a day float trip, likely on the Snake when we¹re in Jackson. Sure
they'll be fishing and she might do some but I want her to see the
countryside as well.

Any guides come to mind that would be recommended?

Looks like Baetis, Terrestrials and Caddis on most of the hatch charts
but fly suggestions will be open with welcome arms as it gets closer.
