You may think you've seen what Yosemite looks like because it has been so widely photographed and captured in paintings, but nothing does it justice like seeing it in person. Stay in the park (ideally in the valley) for convenient access to lodging, food, hikes, and more, in addition to the scenery. The park can get VERY crowded around holidays, but luckily most waterfalls flow into the valley year-round. Check out Glacier Point for incredible views, and make sure to take some time to see Tuolumne Meadows for the peace and serenity it offers. We stayed in the valley for 3 days, and as we left the park I was already planning how and when to come back again.
