However, if my connecting flight to NRT gets cancelled for whatever reason and I need to overnight in Shanghai, I should be OK for 72 hours without a visa right?
You don't mention your citizenship, but I'm going to assume US since you're based in HNL. If this is the case, the bolded segments are fine for 72 hour TWOV at PVG. If not a US citizen, double-check that your nationality is eligible for 72 hour TWOV. Almost all nationalities are eligible for at least the standard 24 hours.
