Sorry for the lazy abbreviations!! ;)

The wife and I are planning a rather vague road trip with the thought of staying in motels wherever and whenever we get tired, but I need to have some kind of plan.
I have a few thoughts about which way I want do to this trip, so heres the basics :

Land in LA April 7th, leaving on the 8th.
Must get to Indio April 16th, late in the day is fine.

I'd like to do :

San Diego area for 1 night.
Vegas for about 3 nights.
Grand Canyons West Rim for a day/night and possibly another day if its fun!
I don't know what else to see thats unmissable?

The order we do them in isn't important.

Heres a map with some directions I was toying with, ignore E -> F as that isn't important!


Any help would be superb!!
