Everything is the same now. Once you tap into the park you go into the hub and the CMs scan you for EE eligibility at checkpoints near the FL path and the TL path. When they wave you through you just head over to your first attraction and you are lined up outside of the queue for it until it gets closer to EE start. When they let you into the actual queue depends on the ride. Idk about Pan but Mine Train they sent us in a few minutes before EE officially started. I remember getting off it right when 8:30 hit.
tbh regardless of what you're rope dropping I still believe in being at the park 1 hr before EE start to be front of park. At MK nearly everyone going to FL is headed to Mine Train so it's not the worst thing ever if you're trying to go to Pan instead and are a bit further back, but I would still aim to be front of pack for my first attraction regardless just because it puts you in a better position for subsequent attractions. I always say it's not about the first ride but ride 2 and 3. Front of pack means you're 1 step ahead of the rope drop crowds and can get off rides faster, and that time savings snowballs as the day goes on.
