I think the most viable way of getting a stellar photo of a place you really enjoy is to photograph it several, or numerous, times. Why did Adams do so well with Yosemite? Because he LIVED there, that's why, and lived their for nearly his entire adult life.

The landscape changes dramatically with the seasons. Vegetation changes in texture, colors, contrasts all change, sun angle changes. Then there's the daily variation of clouds. Although it does happen, chances of getting a real stellar shot on a one-time visit slim.
