Yes it does. I was there last week and got to ride it 3 times (it is great). There was an entrance marked "Single Rider" but was blocked off at the time. There was not much of a wait (maybe 10 min) and fastpass was working also.
Yes, but I don't think the singles line has opened yet. That's what I was told last week. However, each time that I was in line, they did ask for any singles, who got to get on the ride sooner.
