If you are looking for accommodations IN the park, the Yosemite website is the place to start. I noticed some Curry Village openings @ end of August! Lots of places outside the park as well. NOTE - Some places advertise "Yosemite" but are an hour from the park entrance! It can take ~45 mins from the park entrance to get to the valley floor, so you are now an hour and half or MORE to the Yosemite Valley Floor!! Where is your favorite place to stay or camp?!
I always recommend starting with the Yosemite NPS website here.
