For we aliens the experience is about the same. Now we're actually somewhat better off than US residence.
Everyone has to report to customs and immigration before the ship is cleared. The aliens line ups were much shorter than the US lines.
We travelled in January without any problems. We are also going to be on Explorer on Dec 8th, and don't anticipate any difficulties. As a Canadian living in the States, it hasn't been much more diffcult to travel, as I have been flying pretty well every week since July.
Everytime Kuki has to jump through hoops his antlers get caught!
BTW I was pleased to see that Kuki left Explorer in excellent shape and the crew still functioning. They even managed to remove all the graffiti ("for a good time - Kuki at muster station 6") before we boarded.
