Where to stay on route to San Diego... Palm Springs or Joshua Tree?

[nickyjw]

We decided our holiday to Japan this August wouldn’t be what we wanted it to be even if things open up in time, so we sadly cancelled and have booked a trip to California over New Year in hope that this might actually happen, we’ve booked flights with BA so can alter if we need to.
Anyway, I’m just looking for advice on the best place to stay for the night on our way to San Diego. We have 2 nights in LA, then 4 in Anaheim for Disneyland and then we want to visit the Joshua Tree National Park and Palm Springs / Tramway before finishing our holiday in SanDiego. Would we be better leaving Anaheim and driving straight to Palm Springs in the morning and then going to Joshua Tree in the afternoon and staying there for the night... or the other way round, Joshua tree and then Palm Springs for one night?
Am I right in thinking we will have to double back on ourselves either way to head to San Diego?
We are happy to just spend a few hours at Joshua Tree, we don’t want to go hiking or anything.
Appreciate any advice anyone can offer... we did a big month long West Coast trip in 2018 but didn’t see San Diego, Palm Springs or Joshua Tree so this is a bonus break if we get to go!
