"Genius" only requires a little reading
If you look up to the second response you were given, you will already see a full list of cities that have been recommended as stopping points. You can click the "Lodging" tab at the top of the page to see what you can find for budget motels in each of those places. If you look back at those recommendations. That list also included a second list of cities if you decided to leave a bit later on the first day - which would apply if you are planning to leave at noon.
If you look at that list, you'd also see that the 5th day is a bit shorter, so If you leave on Sunday, you still could get to Calgary by Thursday Night (and if you can arrive on Friday, like you said before, you're in even better shape) - you just couldn't plan to get there on Wednesday like you had previously been saying.
No one is here is saying you have to be rich to do this, but we are saying that it's not worth doing something every bit as dangerous as driving drunk in order to save $50 by avoiding one extra night in a motel room.
a little thought and a little planning goes a long way
The new plan you've come up with actually has you driving less each day than the stops that were originally recommended, and this time it looks like you've paused to look at a map to make sure your hotels are actually on your route, so yes, you should be in good shape by sticking to this plan.
Congratulations and safe travels.
