This post is not too easy to translate.
But in brief, this young French person will be doing a business internship in SF, from May 5-July 5. She/he would like to visit Yosemite, DV, LV and the Grand Canyon. Flying in and out of SF. (As far as I know, this trip is not possible, unless she uses a tour service such as Green Tortoise, which does run tours out of SF to both Yosemite and DV. That was going to be my suggestion, as well as seeing if there are DV tours/day trips available from Las Vegas.) Anybody have other ideas on how a young visitor without a car, and on a tight budget, might visit those places?
She'd like to add just a few days to the trip, as far as I can tell (I'll ask).
She has the idea that she can take a bus everywhere, including sleeping on the bus. She seems to think that she'd like to:
"Starting 6 evening in SF. Take a bus to Yosemite Park, leave after eating in the evening, sleep on the bus to save hotel money, go to Death Valley to spend day 8. Then take a bus to Las Vegas and stay two days with overnight stay in a hotel .
My problem here is ,are there bus routes that go where I want at night ? If yes then I find or can you give me a price range ? Could I find safe place to deposit my suitcase for the excursions ? What price do you think this type of Road -Trip can be done?
Do you think my viable route or not ?"
