Important USGP Shuttle Info:
Just FYI, in case you plan to use the shuttle service from the Convention Center to COTA, it's two-tiered this year: $10 per person for standard service, $25 per person for 'Express' service.
The "Express' bus drops you off by the Grand Plaza. The 'Standard' bus drops you off out in the boonies, a 30+ minute walk away from the Grand Plaza entrance (about twice as far as the long walk to Lot F). God help you if you take the Standard bus and your seats are anywhere but T12 or 15. You're looking at a very long walk.
****Here's the important bit, though...if you want the $10 'Standard' service, tickets are
available only via online pre-order, and only through this Sunday, 18 October.
After that your only shuttle option will be the $25 'Express' bus. Tickets for the Express bus will be available online and at the Convention Center on the days of the event.

IIRC, last year the $10 tickets were available throughout the weekend at the Convention Center. Not so this year. If you want Shuttle service this year and you wait beyond the 18th to purchase it, you'll be left with no choice but to buy the more expensive $25 per person Express option.
Vance has written up a nice piece covering all the shuttle and parking options for this year's USGP, with links to various COTA pages on the topic.

If you opt for the $10 Standard shuttle, you'll be dropped off at the McAngus Road shuttle lot (the unmarked gray shape in the top left corner of this map).
