I was thinking about doing a mrtw in NA. Origin: YOW, Destination: HNL, Stopover: YVR, with layovers in between, but I've heard that layovers can only be max 12 hours in NA? Is this true, I can't find a reference to it besides a few folks on reddit. All the mrtw talk from PoT refer to 24hr layovers, couldn't find any posts about anyone trying to do a NA tour!
