Hello to all you roadtrippers.

We are a British couple in the early stages of planning a 30 day road trip from Chicago to SF in September this year.
As you can imagine we are quite excited about this and may be getting carried away a bit with what we are trying to achieve. So I thought I would pass it before your experienced eyes.

At first the plan was to drive the whole way but we are wondering if the drive between Memphis and Pheonix via Oklahoma would be too long and 'boring'? so decided to drop down to Dallas and fly to Pheonix before continuing.

Chicago - Nashville - Memphis - Dallas.
Fly to Pheonix
Pheonix - Las Vegas - Santa Barbara - Highway 1 - SF
(obv this is the bare bones of the trip will flesh out as we progress, but I hope you get the gist)

So:
Is this too much for 30 days?
Are we missing much by flying between Dallas and Pheonix?

I'm sure we will pick your brains as the planning progresses.

Thanks in advance
