Thanks for your report. I'm flying in there for the first time next month, and was mildly curious about border control formalities. I'm more curious about the departure facilities on offer. While I don't want to get my hopes up, I'd like to think that a decent restaurant or two has set up shop (Hongqiao moved up from a 1 to a 2.5 on my 5 point scale when T2 opened there).
The shear thought of connecting at PVG has always sent shivers up my spine, and based on your account, I suppose this will continue to be the case.
