Bank Test Track before it climbs past 75
Guardians of the Galaxy: Cosmic Rewind opens around 60 minutes and only gets pricier from there, holding near 70 through the day and climbing to about 85 by evening, so it's the first standby line of the morning. Test Track is right next door and climbs past 75 by late morning on its own, the steepest climb of anything at EPCOT, so it's the second stop, not an afterthought. By the time you reach Soarin' Across America and Spaceship Earth, both have already settled into their own daily plateaus, near 35 and 25, but neither climbs much further from there, so bank them right after instead of saving them for later.
