Planning on heading to USA May 2014.
1) flying into Chicago - start of May
2) few days there
3) train to Seattle
4) few days there
5) pick up car
~ 40 days of mystery
99) Fly back from Chicago - end of June
Between 5) and 99) key points
c) Las Vegas
d) Grand Canyon
e) Bryce Canyon
f) Monument Valley
Should I try to fit in a drive back to Seattle, via Yellowstone, then fly back to Chicago to pick up flight home ..... or ... leave car in Las Vegas/Denver/Salt Lake City and fly back to Chicago then home ? I'm aware of one-way drop-off charge - but doesn't seem so excessive that I'd need to avoid it.
travelling alone and I can't camp!
I think the Yellowstone route is viable - I just wonder if it would be better to spend more time on the other parts of the trip as it would appear to add several days of long drives which might be better spent elsewhere.
