The two sites I've had there have both had decent shade. I will caution though, prepare for severe wind. Gusts and steady wind strong enough to carry anything that isn't heavy or is aerodynamic.

Restrooms are nice, as are sinks outside. The visitor's center next door has frequent lectures and films. If you miss civilization, the resort has stores that are about a mile walk.

Don't camp in the late spring, summer or autumn unless you know what you are doing and are familiar with desert camping and extreme heat.
