Ever dream of visiting Michael Jackson's Neverland Ranch? No? Well, he's inviting 500 deep-pocketed guests to do just that on Sept. 13, when he'll host a carnival-like dinner party on his $12.3 million estate in California's Santa Barbara County. Tickets for two will cost $5,000, with $1,000 from each sale going to children's charities; the other $4,000 will be applied to Jacko's Visa card debt, um, I mean will cover party expenses.
