Hi Everyone,
i'm planning with my girlfriend to do the road trip from Dallas to Las Vegas in mid of July 2017 in 2 weeks

We have some ideas like Start from Dallas try to go down to New mexico then going back to Amarillo then Albuquerque
drive through (kayenta or flagstaff) and from there visit the Grand canyon and at the end spend some time in Las Vegas

Do you have some advices of what places we can visit?
it's enough time?

thx
