We loved this wonderful retreat. We can't wait to go back. It's a perfect location to access JTNP, but also far enough away from other tourists. The star gazing was a highlight and we preferred it over the night we sky watched in the park. The bed is comfy and the decor was lovely.
Twentynine Palms is cute and has all you need. We loved GRND SQRL and the White Vinyl record store. If you love used books, Raven's is great too. There's also a Grocery Outlet and Stater Bros. if you need to stock up on food.
Before you go, research "Jackrabbit Homesteads" and Wonder Valley so you know what all the little cabins are. It's fascinating!
Our only difficulty, as other have mentioned was the gate lock. If you arrive in the heat of the day or at night, it will be a challenge - especially if you are, ah hem, past a certain age. I think the sand blows into these kind of locks and makes it hard to turn and the numbers wear down. Maybe a button style would work better than the spin type.
