The rule for this thread is to come up with a creative idea for riding headliner rides at night during a busy week without having to wait long in line!
Get a line warrior in your group as he gets near the front, fake a heart attack, when the EMTs/CM comes to assist simply follow them like you belong there.
Make friends with a CM, look for which rides they're working the FP return line, go sneak through with them.
Personally I think the issue here is that yeah there are people who are being "self-righteous" by mentioning the new policy. But seriously you're asking how to do something which by definition isn't going to happen anyways. (i.e. how to avoid lines, on crowded days at the park)
Some ideas that come to mind.
*first step is when the policy officially changes, find out what the latitude will be then try to rework a strategy.
*perhaps change YOUR plans for how to tour the parks, obviously your old strategy of grabbing fast passes early, go rest up for the afternoon, and use them late isn't going to work. So perhaps don't go rest up in the afternoon, or don't do it until you get the FPs you want.
*on crowded days there's a VERY good chance FPs will be distributed well before your rest break for the premium/headliner rides, so getting a FP for the evening will still be possible
*To try to get multiple evening passes, learn the how the rides work and which ones will be more crowded than others, as a results try to predict how quickly the FP return times will advance throughout the day, get whatever apps for smartphones, or keep circling by rides to glance at the FP return windows to do this.
ExampleLooking at DHS, obviously TSMM will be your first one to go belly up, maybe as early as 10am-12pm, 2 hours later run by RnR check the times, if you're lucky there will still be FPs that you can snatch up for later in the day, go back to the hotel and rest, come back, try to hit ToT see if FPs are available, grab one, then look at your times and know where you need to be, Fantasmic or any other shows are out of the question though. You might hit the 3 headliners with this strategy, it becomes a little harder in places like MK with multiple headliners and none of which get distributed super early like TSMM or Soarin'.
*Understand you're not going to be able to avoid all the lines any longer. The rules have changed, so you need to adapt to them.
*Instead of an afternoon break, have an evening break. Be done with the parks by 5pm, hit dinner, rest up for the next day. If you need to see fireworks/shows come back later for them.
*shed a tear as you realize you'll never be able to experience the park how you like to every again... unless you go during slow periods in which cases, FPs? Bah for sissies I tell you!
