We have not camped in YVNP since our girls were young(1970's). We had a home down in Mammoth Lakes for a loooong time. Bodie is fantastic but not as it was before the Cal. Park Service decided to rewrite history. A good friend knew the owners granddaughter and spend summers there. A young girl wrote in her journal, "Good-by God, I'm going to Bodie", the park dis-service wrote "GOD" out of the T shirts they sell at the store in Bodie.
Mono Lake Visitors Center is worth a few hours and on the East side of the Lake is Adobe Valley and the wild horse herd is now over 250 mustangs. Our first GPS was stolen and all our way points were in there so you're kind of on your own on exactly where to look for the horses.
Green Lakes are a bit of a hike but are worth the hike, catching brookies on worms is easy if the kids like to fish. It is an uphill hike.
Enjoy!
