Hi Dave
Thanks for the reply - really useful information. I had written off staying IN Death Valley but the point about the cooler parts of the day is really helpful.
I had assumed that SF would be a cheaper option for flights. We want to avoid LA but will fly to LAX if it is significantly cheaper. I guess it isn't too bad a drive from San Diego at the end of the trip either.
Another option was flying to Phoenix and starting there. I'm feeling torn as it looks like a lovely drive to GC via Sedona but if we're to avoid doubling back, we would continue round the loop and miss out the Hoover dam as we go Bryce to Zion to Vegas.
Any ideas on how flying to Phoenix compares pricewise to Vegas or LA? And any thoughts on which is preferable - seeing the Hoover Dam, or seeing the scenery going from Phoenix to GC??
Too many choices!
