Palm Springs Suggestions?

The day after I get to LA, we are taking a trip to Palm Springs...which I am super psyched about.  This trip has been on my to do list for several years...

I'm looking for suggestions on things to do/see and place to shop while we were there.

I'll be following Domino's Destination Palm Springs Guide, Design*Sponge's City Guide , and Kelli's Guide to Palm Springs {Thanks Kelli!}...

Anything I should be sure not to miss?
