i have just discovered this site and it's fantastic!
We are an Australian family visiting US for Christmas - two small children (3 & 5). We have nearly a week in December (16-23) available for a road trip from Las Vegas.
I would dearly love to see Monument Valley, but am concerned about the driving times and realistic sort of itineraries that allow for some sightseeing and enjoyment, rather than just ticking off places. We don't mind driving for 3-4 hours at a stretch, but don't really want to spend 10hours in the car everyday.
Any advice on what we can/can't include would be good.
We have been to Grand Canyon before, so could conceivably leave it off, but would like children to see it if possible. a night at Vegas to end would be good too.
