Of course the page here has great content, and cool photo of the bird imprint that caught the rabbit (or squirrel), but I really like the layout of this page too. Very nicely done and aesthetically pleasing!
While I didn't take that route, it seems like a reasonable option. You'll likely have plenty of snow in early May, but nothing intolerable, and I agree the distance from Hall Valley seems similar to the distance for the route I posted. I suggest checking to see if the campsite is open for the season prior to planning on parking there. It should open Memorial Day weekend, FYI.
