I will brave Guardians this September, but for me Crush is guaranteed motion sickness, I cannot ride it at all without a tablet. For comparison, I can do without an issue BTM, Remy and other trackless dark rides Slinky Dog, Space Mountains and ToT. Rock and Roller Coaster is a bit of a gamble, but I can manage.
It's not intense or fast, it's a family coaster, if you don't suffer from motion sickness you'll enjoy it. The problem is the spinning in one direction while the track goes another which for me is a big no. I think I'll have to take a table for GotG, any suggestion for a non drowsy one is welcome.
