Epcot: 9am open, 9am Garden Grill Worth It?

If Epcot opens at 9am, if we had a 9am Garden Grill res, would they let us in with the early ADR folks, or would they make us wait till 9am? I switched days for Epcot & DHS when I was doing FPs bc worked better with those, but screwed up my dining stuff a little. Contemplating just ditching this one.

You can probably get in 20 minutes early, but they might not seat you until 9.
