Runners are fine. Just have everyone enter the park to activate and then send one with all tickets like you normally would do for Fast Passes to get in line. I did it for my family, went through the turnstiles and walked as quickly as possible as far up the line as I could. Interesting sidenote, they have CMs standing there to put your tickets in the FP machines and grab the FP's. Made me wonder if you could actually get more than one per ticket if you did it yourself. Probably not, but I wonder... I think they do it for you so no one can come back and say, I have 5 tickets but it only gave me 4 FP and sneak another one. Pretty good crowd control, but better get as far ahead in the line as possible, or it will be a long wait (just imagine 4,000 people in line at a FP machine...)
