That latest schedule still looks so tight, to me, that I don't think you'll see a lot in some places, I think you're still being optimistic on travel times, and there's no provision for the unexpected, which often happens (at least to us). For instance:
7/26 - West Yellowstone to Jackson WY 7am to 1pm. Tour Tetons in afternoonYou won't see much. If all you intend to do is drive to the lake and view a little scenery, then you might be OK, but two full days will just scratch the surface, let alone four or five hours in the afternoon (if you get that long).
Granted that you'll have several days for Yellowstone, which may work OK for you.
7/27 - Jackson to Cody 7am to 3pm. Tour museum and beartooth highway in 2 daysI'm not sure you can make it that quickly since the speed limit for much of the trip will vary from 45 mph down to 25 mph, so you'll not see very much of the museum or else you'll not drive the Beartooth, which will likely take most of the day -- remember, it's slow going and you'll be lucky to average 35-40 mph, less on Beartooth itself.
If you like country music, especially the more western variety,
Dan Miller's Cowboy Music Revue is very much worth seeing, a nice dinner and a great show at the museum in the evening. There are several other attractions in Cody that, to me, are worth seeing, too.
7/29 - Cody to Ft Collins KOA 6am to 2pm. Drive through RMNP.If you get into the KOA and settled in camp by 2PM, you'll have time to get to the RMNP entrance and spend an hour or two (it's not a 30 minute drive) in the park before heading back to Ft. Collins. RMNP is huge, though not as large as Yellowstone of course. I'd suggest eliminating this side trip, save it for the future, and allocate that time to seeing other things.
Perhaps I'm a tad pessimistic on the time element (and I didn't comment on some other areas I think are too tight), but I think you're trying to fit too many things in. You might also keep in mind that traffic can be a problem, not counting any bison jams or bear jams (traffic and or animal slowing you to a crawl). But I wish you well, and hope it works out better for you than I'd anticipate, and that you don't get as worn out as I suspect you will on that schedule. Luck...
