Are you going to actually be at DHS on a SWW day(Fri, Sat or Sun)? If yes you need to plan to be there at least an hour to an hour and half before the park opens. They will open the turnstiles early and let you go so far into the park. We have been to SWW the last three years. Last years seemed to be the craziest with all the people trying to get into Jedi Training since they didn't pick from the crowd any more but were doing sign ups. When they let you in so far you will need to head toward the left like you are going to the Sounds Dangerous building (unless they change it up this year). There you will have to wait until the CM's drop the rope at 9:00 AM. Last year they introduced a couple of CM's you followed one for the Jedi Training or the other for Padawan Mind Challenge (DS wanted to do the PMC). People are crammed in this area like sardines......when the rope drops (despite all the warnings of no running, no pushing, etc......it's crazy) it was chaos. We were able to get in the PMC we wanted with no problems. The line for Jedi Training was probably worse than the line for fast passes at Toy Story Mania first thing in the morning - I am sure they filled up all the shows for the day and turned people away there were that many trying to get in. I think the kid has to be with you for this......I am not sure.
Get there early. There will be CM's outside the turnstiles handing out the special SWW maps/brochures and last year they were great about answering any questions of where to go for what sign ups etc. and if they didn't know they radioed and got someone who could help.
Good Luck!!!!! And may the force be with you.
If you are going on a non SWW day I think it might not be as crazy but I think you still go line up and get selected for whatever show. I'm not entirely sure. Maybe ask on the general theme park board and see what the current process is from those who are just back.
