My TP is suggesting I need a fast pass at HS for Indiana Jones Stunt Spectacular and Lights, Motors, Action! Is a fast pass really required or is it posted because you are to arrive 15 minutes early for the show?
It is not saying that you "need" a FPP; you probably don't have anything else with a particularly long wait time that you could get an FPP for, so it is the best use of one of your remaining FPP opportunities. You can most probably get into the show without an FPP.
This might be a case where it makes since to go into the website (not the app) and cancel one fpp so that when your first two are done you can go make more at a kiosk
