I think the case that the limit has been upped is still not settled.
Martin keeps saying that hasn't been the case. Those who say the limit has been upped do so based on how more crowded the parks feel, which could be that crowds previously weren't bumping up against the lime, but now regularly are doing so.

Some park capacities have been raised. I’ll say by around 10% of their earlier caps more or less.
DHS is not one of them.
