There are too many to list, since you can find a tree or a nice branch in the valley or above....and you can do a lot with it.....assuming you know what you're doing. You can also use the iconic spots like Half Dome, Glacier Point, El Capitan, etc. I was able to pull pretty good Milky Way from a v. little known campground (6300' elev)....and probably could have done it better if I used my 50mm at F2.
My advice is to get to the park in the daylight (2-3hrs to spare) and check out the locations that you are after.....so you are familiar...whether you need to do a hike to grab the required spot or shoot near your vehicle.
Both, Half Dome and El Capitan are on the valley loop....soo your driving is not extensive. You'll be given a map at entry point. If you are "borrowing" campground space (I found the best view from one site) make sure you alert the folk that occupy this spot (explain your situation)....or they might mistake you for a bear :>). I didn't mention falls, since extended shutter (over 3-4 seconds) is not v. friendly to water.
Enjoy your trip and post some shots when you get back.
El Capitan....as viewed from rd to Fresno....you could get closer.
