That was me on some days when I was only in the park for headliners. No parades, no character meets, no Dumbo or Figment. Headliners over and over.
Going forward I think it is going to depend more and more on how long we are willing to stand in SB line. I certainly don't think it will be possible on crowd level days of 6 or more, because WDW is encouraging everyone to use FP+ on a scale we've never seen before with the paper based system. By the time you've ridden any headliner twice you might see extended SB waits and no more FP availability.
It would certainly be possible to ride ONE headliner two or three times, but anything beyond that is going to require substantial waits in standby. Look at yesterday and today, for example, where EasyWDW has both days at 8's and MK wasn't recommended on either day. The reports coming back so far about MK sound and look disastrous.
Crowd levels of 5 or less? There will still be opportunities throughout the day (RD, EMH, during parades) when you could ride multiple headliners multiple times. Although before we could pull multiple FP's, now it's going to be multiple SB's.
Days when crowd levels are 3 or less are going to be the only days left where people like us will be able to ride EE 5 or 6 times while the Standby line was still 10 minutes, then head to another park and still be able to do ToT or RnRC several times, then maybe even head to MK and do two mountains in the evening.
Disney is pushing everyone out in equal force to all attractions; what that means is we will have increased opportunity to experience more attractions but less opportunity to experience the same ones multiple times.
