Uncas;
Top of the morning to you sir, I hope wherever you're at the heating system is functioning properly and you're well.
Regarding the question at hand, are you thinking somewhere like Prince George for a half way stop or are you going to slice it into smaller days?
We drove up to Dawson City this summer and did book our hotels ahead of time online and were glad we did. I'll find the name of the place in Prince George, but it was full to capacity on a Thursday night as were all the rest of the hotels which was both good and bad in some ways.
When we're booking a hotel, the online reviews seem to be pretty accurate overall we've found.
Will the trip be in summer or now in winter?
Either way, if you hit up the DriveBC website it'll give you up to date road conditions including fires, accidents and weather.

Safe travels, Merry Christmas and Happy New Year to you.
