Hi Brothers and Sisters. I'll be reviving this thread again as my family and I were planning for a similar route trip this September of this year.
I would ask if this following trips are feasible within 3 weeks.
Take note of our following routes an option 1# Home Base: Seattle
Route - Go to Banff, AB from Seattle. To stay in Vancouver or Kamloops for a stopover before going to Banff. Stay at Banff then proceed to Glacier National Park in Montana, stay for at least 2 nights, go road trip to Billings in MT for a 1 night stop before proceeding to Mt. Rushmore National Park for 3 nights including a visit either on Custer and Badllands National Park. After that, we proceed to Denver in Colorado for the Rocky Mountains trip for another 2 nights, then proceeding to Mesa Verde (stay in Durango, CO or Monticello, UT for 2 nights) then proceed to Salt Lake City for a night then proceed to Grand Teton (stay for a night), Yellowstone (2 nights). Go to Missoula (MT), stay for a night, then to Spokane, WA (1 night) before going back to Seattle.
Option 2# Stay in LA then fly to Denver CO (forget about GNP and Banff), stay for 3 nights for a Rocky Mountains trip and Mesa Verde Trip, then after, we proceed to Mt Rushmore, stay there for 3 nights including trips to Custer State and Badlands, then proceed to Sheridan/Casper, WY (stay for 1 night) before proceeding to Grand Teton (1 night), Yellowstone (2 nights), drop by Cody, WY, proceeding to Bozeman then to Missoula, stay for 2 nights, then to Spokane, WA (1 night) before going to last stop in Seattle.
Option 3 # Same as option 1 but after Colorado trips, proceeding to Albuquerque in NM for 2 nights, Phoenix for 2 nights, 1 night in Kingman, AZ before returning to LA.
Your suggestions will be well appreciated.
Thanks and God bless!
