Thanks Beth! Curious, do you know if group 24 kept them from boarding before 12:00? I think when I was there they were calling group 30 something before noon. Thus, even if you have a later PAT time, getting there early might get you on the ship sooner than if you go closer to your time. Of course, I know that sometimes people with later PATs can't even get into the building if it is too crowded. So I'm not suggesting everyone should show up at 10:45, just that they might want to beat their PAT times by 15 minutes or so.
Also, on the subject of arrival process, I found it quite convenient (as some here on this board suggested) to drop my family and all the baggage off at the port, and then go back and drop off my rental car. This way, it was a lot easier for me to catch a shuttle back from the rental place (one person, no bags, instead of my whole family) and in the mean time, they dealt with the checked bags, and went through security. They did wait for me to do the check-in process, but I'm not sure if they would have had to wait. Still, it made it go faster for us. It made it less crowded for others at the rental place too. So my thanks to those who suggested it! Several families at the rental place told me they wish they had thought of that, so I mentioned where I heard of the idea! Right here, on the DIS boards.
