It sounds hit or miss if you get to see the pre-show. My family went last Friday (4/30) and there was no pre show for us. I had looked at no spoilers ahead of time so did not realize we missed a whole section until we got home. If you want to watch the pre show beforehand to make sure you know what’s going on, stop watching when the doors open and you see storm troopers. We bypassed the pre show room and only walked through the room with the storm troopers; we thought they were just for looks, the pre show would’ve made more sense why they were there. We were able to follow along with what was going on but the pre show would’ve really tied it all together.
