Preparing to head home

We have enjoyed a fantastic week on the island. Now it's time to start thinking about heading home. We are wondering what the liquor limit is for the plane. Is it a limit of 2 liters?
What's the earliest we can check in our bags? We would like to drop the bags and go get one last good meal before boarding the plane.
As always thanks for all the wonderful advice and recommendations from the TTOL community.

First do you have a direct flight? If not then you will need the tsa approved bag for the liguor if you want to carry it on the plane. Otherwise it has to go into your checked bags. 2 liters are fine, generally you can take more, just declare it.

Check in depends on the airline. AA is open early, others depends on when their first flight is.
