Hi, we are from Brazil and we are planning our trip in August-September.

Already read some posts about these three trips we have to make but didn't find the best route.

We have to do a one day trip from San Diego to Grand Canyon. We can leave very early, and probably gonna need to.
We are two drives with some experience. Wanna to stop to have lunch and to pee some time. But we can use some diappers if necessary to make it in one day... lol

The other trip is from Grand Canyon to Las Vegas. We gonna be at the South Rim.

Them we gonna leave Vegas in direction to Mammoth Lakes. We wanna pass throught the Tioga Pass, but I don't know if it is possible. If there's another scenic route to make, we are open to it too.

I hope you can help us with that. Specially with the trip from SD to GC. We are start to feel scary about not making it because of the amount of time travelling. But there's no other way... the reservations are already made.

Thank you very much!
