Celebrity retreats

I've wondered where celebrities go to get away from crowds and work. Where do they hide out and go on retreat?

The media will report that they've gone to Europe or Africa. Sometimes, we hear they've gone to lake Tahoe to a private lodge or cabin there. Maybe they stay home and just don't answer the phone. Or maybe they even take advantage of Pigeon Forge cabins, where they can lay low and just rest for awhile.

God any opinions or news about this?
