yes -
but in the morning EMH...one hour before opening? you won't need them.
in the evening, however, it's best to get a fastpass BEFORE EMH truly starts. The "come back" time will be INTO the EMH hours...and only those who have their bracelets will be able to get them.
We stood in line forever during EMH for Stitch.. Practically took up the whole EMH time - whereas if we would have gotten a Fast pass...we probably would have been able to do a lot more...
