Transfer in Guangzhou to Bali

Hello. We are flying from SFO to Bali via Guangzhou. Our layover in Guangzhou is 13 hour and we have 2 year old twins. We were hoping to use the transit visa to get the hotel offered by China Southern. My question is the visa for Bali. We are intending to get it from the airport upon arrival in Bali. Can we still get the free 72 hour free transit in Guangzhou if we don't yet have the visa for Bali? Thank you!
