Yosemite: I want to go to there...

We've been to Sequoia in the winter/early spring but never Yosemite. We have spent several summer weeks in Yosemite and we've always camped. I know it would be too cold to camp in the winter but staying in the lodges can be quite pricey. I would love to visit the valley when there is snow on the ground, I imagine it would look like a winter wonderland. Hmmm...maybe if things go our way, we can make a 3 day trip and stay in the Wawona Hotel
