If you have an early flight just let guest services know as soon as you board the ship...after us of course. Anyone with an early flight it allowed to Disembark first. It should be a problem. Most people have said they were off the ship by 9am.
We filled out all the paperwork with our flight info, our TA put it on our reservation and they told us to check the night before we get off to confirm we'll be in the first group off so I'm sure it will be fine (they got in early last time so that made me feel better) but I just want to make sure as I don't want to miss my flight.
