Last summer, I found the Nursery and Breakfast, like Bed and Breakfast, from a website. It is located in Shasta Lake, California, which is about 4 hours from San Francisco. If you want to spend a night there, you will pay 40 bucks for one night, including free 1 adult diaper, 1 baby bottle, and free digital pictures saved to a CD-R floppy disk. In addition, a mommy or a daddy can change your nappy during your stay and feed you breakfast or you can feed yourself if you wish. The Nursery and Breakfast is hell lot of cheaper than private babysitters and mistresses.
Here is the website of Nursery and Breakfast, http://www.nurseryandbreakfast.homestead.com/
I think it is very interesting and sweet.
