FoP Rope Drop Question

We plan on RD FoP on an EMH Saturday morning in December. We are morning people so plan on leaving resort at 6:20 by car. If we do this I have heard that they take you through the FPP line. My DD said that what you see waiting in line is a really cool part of the attraction that you don’t want to miss. Any experience with RD FoP ?

We went through part of the FPP line at RD. We didn’t see the lab, which would be a cool part to experience. I don’t know when the CMs start putting guests through the full queue.
