The trip to Alaska was just as enjoyable as Alaska itself. . . I would skip the bus tour to Denali, after the trip everyone wanted to take a nap, I went back on my bike and saw a lot more animals close up. 
 I agree with you about seeing as many national and provincial parks in Canada as possible on the trip because they are often spectacular.  And the Stewart-Hyder area glacier and wildlife alone are well-worth a trip over the Cassiar Highway in one direction.
I'm sorry but I couldn't ride my bike past the Teklanika campground when I was younger, much less up Polychrome Pass to the Eielson Visitors Center or Wonder Lake over 150 RT miles of gravel road.  So, if you are not a bike aficionado, take the Denali NP bus tour. I have taken it 3 times--1992, 2000, and 2013--and have never been bored, even if the bus itself can be tiring.  And keep in mind that, because summer days in the park are long, even a bus trip that seemingly starts late in the day will generally get you "home" before dark.  
On one Denali bus trip, the driver was a Ph.D. wildlife biologist from a university in the Lower 48 who spent his days off studying the park's Dall sheep.  He spent our entire trip essentially teaching a class on the park wildlife for all of us.  Having never had college biology, I learned more than I ever could have from a guidebook.  It was, without doubt, the best "guided tour" I have ever been a part of.  IMHO, the bus is worth every dollar of the cost, regardless of how many people are in your family/group.
