I had a work trip to 29 Palms to work on the base for 10 days or so. The hotels were close to full and some of them out there are questionable. I decided to look at VRBO and found Lucille. I don't think I will stay in a hotel ever again on my trips out there.
It is off the main Hwy, so it is very quiet. But it is less than a 2 min jaunt or 10 min walk to the main hub in Joshua Tree (which is a phenomenal area btw). Plenty to eat, do and see or shop. The Crossroads Cafe is awesome and the people are friendly. There is also a very nice quaint coffee shop adjacent to Crossroads. 10 min or so from Yucca and about 15 from 29 Palms. Perfect location.
Additionally - it is 5 min or so from the western Joshua Tree National Park entrance, which is beautiful. I drove through it multiple times en route to the base (the east entrance/exit comes out right at the road that will take you to the Adobe Rd that leads to the base.
The RV: it is small, but was perfect for me. Consider that if you have more than 2 people in your party. That said, it was plenty big enough for me. The AC works just fine, but only needed it a couple hours a day when the temp outside got up to 90 or so. Otherwise, kept the windows all open. Its usually breezy.
The inside oven/stove, refrigerator, and shower don't work. That might be for safety reasons. That said, you don't need them. The outdoor shower is MARVELOUS and very easy to use. There is a refrigerator outside as well under cover and it and the freezer worked just fine. Made ice in less than an hour. My favorite part was the grill. I cooked every meal on it. Baked, grilled, braised and toasted. There is also a side burner to the stove if you want to pan fry or skillet cook. I cooked eggs, beans, rockfish, veggies, and so on. I ate out ONCE the entire time I was staying there and that was to meet a colleague.
Last: Desiree and James were wonderful. I had two minor problems when I was there and they responded immediately. The coffee maker quit on me and Desiree brought me one immediately. And I had an issue with the door lock and James came to work with me on that within the hour. THAT is great stewardship.
If you're looking for a mansion, the quaint RV isn't that. But if you are looking for an "outdoorsy" stay that is peaceful and to yourself with access to all the amenities Joshua Tree and surrounding areas have to offer, this is it.
