Hello, my family is taking their first RT from Chattanooga tn to Yellowstone in July 2016.......also wanting to squeeze in Grand Canyon if possible. I'm starting early on planning because I have no idea what route is best or really now to begin. There will be 7 people going on the trip. We have 2 weeks and want to see some things along the way. I have no clue how much time to a lot for the family at each place. I would like to stop by Cody wy for kids (1.5 days)??? Yellowstone....maybe 3 days??? Also everyone has said go to deadwood co and Laura Inglas wilder homestead......but not sure if that's even close enough to worry with. Then when coming home go to grandcanyon......but I feel that isn't an option on a 2 week schedule ( however my hubby feels like it is). I'm really a blank slate needed some advice for peeps that's traveled and knows if what I'm wanting to see is even possible in 2 weeks. Any info, possible schedules, tips, etc is welcomed. Thank you in advance.
