[Archibald Donnington]

We are taking our first of many family road trips in our X3. What I am looking for is some travel advice from my trusted fellow adventurers. We will be traveling around the middle of March. We are going from LA to Las Vegas (family related), then through Utah, next to Colorado, down to NM, a dash of AZ, then a jaunt through Palm Springs and back home.
My questions are as follows...
Does anyone here have any good scenic routes?
Any ideas on where we must go?
Any reccommendations on world class lodging?
Are there any specific monuments that we MUST see?
And finally, most important, which restaraunts do we HAVE to eat at?
Thank you,
