I’m not sure how you are getting Rider Switch added, but we just enter through the Lightening Lane and as we scan our passes, we tell the CM standing right there that we need a Rider Switch pass. We never waited more than a few seconds for one, even when we were there during Thanksgiving break last year. Sure, if you are entering at the beginning of the LL window it’s not necessary to get one, but I wouldn’t risk it if entering 15 minutes or more past the start time. Things happen - the ride can temporarily go down but not for long enough to trigger an MEP for the people still holding their LLs. A kid could have to go to the bathroom. And there are some rides where you can have a pretty good idea of how long you are going to wait in the LL, some some you don’t (Splash, MF, and Soarin’ are good examples of this). I personally wouldn’t risk losing an LL to save a minute or two by not getting a Rider Switch pass, but everyone has their own level of risk aversion.
