Here's what I've got:
Present day. A well-to-do family lives in a huge, sprawling mansion somewhere in California. What I'd like is for their home to be inside Yosemite National Park, or at least very close to it. The home is sort of isolated; the closest neighbor is not right next door, but probably, I don't know, a quarter mile away? There's a gate around the property. The scenery surrounding the house is of the breathtaking variety (at least that's what I'd like).
All my research shows the following: Most of the people who live inside Yosemite work there. (My characters most definitely do not work for the park.) The most expensive house inside the park that I've found any information on is a "2-bedroom/2-bath cabin for $1 million." My fictional house is a mansion, much, much larger than this. So, do any insanely rich, well-to-do people live inside the park? If not, where do they usually live that is very close to Yosemite? City names would be helpful.
Search terms: "Yosemite," "Living in Yosemite." Both yielded so much info that it was quite overwhelming to look through. And it was all about tourism and how to get a job inside the park.
Edit: You guys are giving me some great information! Thank you! I love being steered in the right direction. ^_^ Keep it coming.
