We stayed here for 4 nights while visiting our parents who live in Rancho Mirage. The resort is extremely clean, well-maintained, and quiet. We are normally boondockers, so it felt decadent having full hookups, daily trash pickup, and all the rest of Emerald Desert's amenities such as sparkling swimming pools, daily activities, free Saturday Continental Breakfast, etc. 

We upgraded to the"luxury" site which meant that the spacing between sites was a bit greater and we had a lovely patch of green grass between us and our neighbors. We have a very small trailer, so our only issue was the distance from our sewer connection and the resort's. With so many nearby stores, it just took a quick online order for curbside pickup at Wal-Mart for extra hose and we were good-to-go. Literally. 

As others have mentioned, Interstate 10 and a set of major East-West train tracks lie right behind the resort, but neither were very disruptive to us. YMMV. 

We will absolutely stay here again and again, and we highly recommend it to others. In fact, we challenge you to find a nicer RV resort anywhere else!
