Because they are letting people into Pandora 20-30+ minutes before scheduled RD (or EMH), the current consensus is to get to AK about 60-75 minutes before then and you will be at the front of the pack.
It is a slow march into Pandora and 99% of the people are going to FoP, so it will go from no wait to hours super fast. But, being in the front of the pack you’ll likely be on and off FoP relatively quickly and then be able to hit NRJ if you want. Typically with this technique you’d be on and off both rides by 15-20 minutes after official RD.
On our EMH day back in August we had a longer wait than most for a couple of reasons: some extra start and stops I think, plus we got stuck in middle of the marching crowd. If you stay to the right and left sides of the path you will likely move much more quickly. I posted of our experience in my trip report, you can see photos of the crowd plus a timeline map I made as reference for people. (Again, most days people will do much better than our EMH experience, think we were just unlucky that day, plus in hindsight think we should have been there 15 or 20 minutes earlier.)
