Fixed Asset Impairment (Details)	6 Months Ended

Asset Impairment Charges [Abstract]
Impaired Long-Lived Assets Held and Used, Facts and Circumstances Leading to Impairment	Fixed assets are evaluated for impairment periodically whenever events or changes in circumstances indicate that related carrying amounts may not be recoverable from undiscounted cash flows in accordance with FASB released guidance. The Company’s long-lived assets and liabilities are grouped at the individual club level, which is the lowest level for which there is identifiable cash flow. To the extent that estimated future undiscounted net cash flows attributable to the asset groups are less than the carrying amount, an impairment charge equal to the difference between the carrying value of such asset groups and its fair value, calculated using discounted cash flows, is recognized. The Company did not incur any fixed asset impairment charges during the three and six months ended June 30, 2012 and 2011.
