Camping in Yosemite

Hoping to get to Yosemite tomorrow. How hard is it to find camping on a Sunday at this time of year? If we can't get a spot at camp 4, where else should we go?

Thanks!

Looks like there are some spots in Upper Pines available starting this Sunday.

They had the signup list at Camp 4 when I was there last weekend. You should be good.
