Am I eligible for the 72 hour visa free entry in Guangzhou ?

Hi, My family and I are travelling from London to Sydney Australia and have a stop over of 11 hours in Guangzhou for which the China Southern will provide us with a complimentary accommodation. Do I need to apply to avail the accommodation( because the hotels are normally outside the transit areas)? If I do will I be eligible for the 72 hour free transit? I have a pakistani passport with an indefinite leave to remain in UK. Thanks
