I have a trip next month with a mid-trip deadhead from nrt-pvg.

I am considering jumping on us rather than taking sched Asiana thru icn. Does anyone have any info on deviating into pvg? For example, how to set up my own ground transportation so that I don't crowd the operating crew in their car... Any idea what the cost of limo would be to the hotel? I will have plenty of bank if I deviate, just wondering how to pay for a limo or taxi and if the ramp might help coordinate.

I've looked in the briefing guide, but more often than not, the information in that has been incorrect.

Thanks for any help!
