We(3 adults) will be driving to YSNP from Kansas City. YSNP and GTNP will be my main focus of the trip, but I also wanted to stop by Denver/RMNP and Rapid City/Mount Rushmore. I will be leaving on May 26th and returning on Jun 4th, so I have 10 days. I see three routes so far: I-70 through Denver, I-80 through Lincoln. or I-90 through Rapid City. Can you guys suggest me an travel plan and places I should visit that I could fit in within 10 days. Also what would be the cheapest place to stay in YSNP except campgrounds. Will we find cheap roadside motels if we don't book in advance?
Mod note. Please keep all questions regarding this trip in one thread.
