I mean, this is why my family (not me, probably - maybe?) won't be returning to Epic for a while.
My dad gets motion sickness. He can barely cobble a full day together at IOA + USO combined (HEx both ways, JPRA, ET, sky trolley are favorites). Mario Kart was ok, Yoshi was...well, Yoshi, and shows were fine. Hiccup's was a one-and-done. But besides eating (raves), he struggled finding things to do the two days we were there (without having to buy a wand, band, whatever). We stayed at Helios so he was able to hang out there while we did other rides, but I felt bad he couldn't do more.
If Epic (or more broadly, Universal) isn't for people like my dad, ok. But when we take family trips in the future with my nephew - growing into the ideal demographic for Uni - we still probably won't visit frequently. He can get more joy from being with my nephew at Epcot, and alternating thrills with things we can do together (and participating in moderate "thrills" like Test Track)
