Most all the locations mentioned outside Death Valley, with the exception of Panamint Springs Resort and Death Valley Junction, are not very close to the Park. Many of them are probably a 2 hour drive each way to Furnace Creek.

Panamint Springs Resort is not a resort in any sense of the word. However, I haven't bothered to check out any of the rooms as I would never consider staying there based on what I have seen.

Death Valley Junction, even if the motel is still operating, is also seriously weird and VERY basic.

Stateline on Nevada route 373 and Beatty are about the closest but they really aren't places worthy of much consideration, either.

Given the encampment is on during the only time you can visit Death Valley, maybe you should not go there on this trip after all and pick a lesser, but available, park like Joshua Tree. Or spend a few nights in the Palm Springs area.
