<human>: So, here's the deal: My mom and dad are getting a divorce soon, but my mom decided a long time ago that she, my little brother, and me would go to some of the southwestern states (We're from Kentucky, and we've been all across the East Coast) whenever I graduated from high school. 

Anyway, I just want to make sure that this trip is awesome for her since she's a bit depressed about the divorce. 

Here's what we have in mind so far (All of this is tentative; these are just ideas for places to go):

We've already decided that we would fly to Phoenix, AZ. Then, we'll take a loop through Arizona, Nevada, and California. 
Some of the cities we have in mind (We've never been to any of these):

Flagstaff, AZ
Las Vegas, NV
San Jose, CA
San Francisco, CA
Los Angeles, CA
San Diego, CA

Of course, we've also thought of some of the parks and other spots to visit, such as:

Grand Canyon
Sequoia
Yosemite
Death Valley
Meteor Crater
even Disneyland

So, redditors, I ask you for some help. Whether it be tips, suggestions, or warnings, I would appreciate any feedback I can get.

Summarize the given text in a few sentences.
<bot>: My mom and I are planning our first trip to the southwest states. I know the Redditors know many more places to visit and much more about the states than I do.
