Yosemite visit

Folks, we are planning on taking our FW for a little trip after April 15 and want to go to Yosemite for part of the trip. We will probably be there around the first week in May, or so. Anybody who has stayed in the area, good camping areas to stay in. I don't particularly want to stay in the park, just somewhere close like Mariposa(sp). We also plan on dropping down to the Sequoia Park on a day trip. Any help would be appreciated.
