Want to buy Hard Rock Park? Well, you will need at least $3.5 million. Documents filed in bankruptcy court show bidders must show they can meet the minimum $35 million price with ten percent as cash, and prove they can run the business. The $400 million, 55 acre park opened in April. It filed for bankruptcy protection in September. The park is accepting bids until December 12, 2008. It will go up for auction December 15, 2008. Park officials have said it will not open in 2009 without a buyer.
