I find this topic interesting. I voted for more beauty but also agree with the Plawrence sentiment that these things are not necessarily mutually exclusive. But after all, since this is a Yosemite website, I would be somewhat surprised if folks here were not willing to tolerate a few extra people.
But I am curious about what people mean by solitude. I can find solitude or would consider it solitude if I am hiking on a trail and pass another party every once in a while. Or if I am camping on the other side of a lake from another party. Does this go back to that crazy conversation about how sometimes people just won't leave you alone?
But to take it another extreme: I can be perfectly content and in "solitude" in the "Quiet Car" of the Commuter Train on the way to work in Chicago. Weeks will go by where I simply find my seat on the train with a good book and read without being bothered or spoken to by anyone.
