My husband, 3 teenage kids and I want to fly from RI to Las Vegas....somehow want to include San Diego, Yosemite and San Francisco in our itinerary. We have 2 weeks in July. Any thoughts on our best route? Is this the correct order of travel?

Any suggestions on any places in between stops? We have never been west of Las Vegas before. Any guidance would be greatly appreciated. If possible, please email me at Jaylista@aol.com.
Thank so much, Jayne
