Can the Early 2016 MacBook (not Pro) Drive Two Thunderbolt Displays?
I should have looked closer to the tech specs on the Apple website:


  Dual display and video mirroring: simultaneously supports full native
  resolution on the built-in display and up to 3840 by 2160 pixels at
  30Hz on an external display, both at millions of colors.


Based on this I can only run my built-in display and one external display, and only at 30Hz.
