Here's the plan!

14 days - three states, more than 1,400 miles in a 4x4, visiting a number of national parks, as well as Las Vegas and San Francisco.

We fly into Las Vegas on 13 March and spend two nights - at the Luxor.
We then drive to a ranch west of the Grand Canyon - where we'll be staying in a teepee.
We drive east to the southern rim of the canyon and spend a day marvelling at the place, staying in a local motel.

Next day it's down south to Flagstaff and after some mooching around we head west along Route 66.
We'll break up the journey by staying in Boulder City - probably.
On the 18th we drive up to Death Valley.
Then its around to Lone Pine - don't you love the name! - and then south and round the Sequioia National Forest until we head north to Yosemite.
We spend two days in Yosemite - it's the part of the holiday I'm looking forward to most - and then head west to Big Sur an the west coast.
After two days on the coast we head north to SF - where we stay at out favourite hotel, the Mosser, before flying home three days later.
A lot of driving. But then the US is a lot of country.

I'll try and post a map showing the route later on.
