Death Valley recommendations?

Thanks, all, for the great information. As many of you had predicted, there is no availability at Furnace Creek, so we’re going to have to look outside of the park. Based on your comments and suggestions, I ended up putting a priority on finding a campground as close to the park as possible. So, this morning, I was able to reserve a site at the Longstreet Casino & RV Park. (Thanks for that recommendation, Acampingwewillgo.). Again, my thanks to all for the good information.
