We took the plunge and booked a 31' class C rental out of Michigan for the last two weeks in August and first in September. We have 20 days of travel available. Traveling with me is DW, DS and DDx2. We are in our late thirties and the kids are 11,9 and 5. The general route under consideration is 90 to Yellowstone than south to GCNP(south rim) than Route66 back home. We would like to take in all the regular sights along the way. Kids won't "hike" much beyond a short few hour loop/tour so we are pretty much road bound. We do plan on three or four days in Yellowstone. We humbly request of ye wise forum sages the following advice?
1. Too ambitious?
2. How many days drive out and suggestions on where to overnight on way to yellow stone?
3. class c around Yellowstone or rent a car?
4. Average driving mile/day recommendation ?
5. Other than 14 and 14a through bighorns any really hairy roads/portions to avoid?
Jeepers, so many questions! These five are a good place to start. I'm a bit overwhelmed. Thanks in advance for all your wisdom.
