We got back last Wednesday, and crowds were low-to-medium when we were there. The theme park crowds, that is. Blizzard Beach was uber-crowded, even 30 minutes after rope drop on a Monday. Typhoon Lagoon was better.
We did see a few tour groups at the parks, but they were not problematic, except for one group of girls who chanted

, but they passed by us quickly. My S.O. pointed out that the chanting is a cultural thing, & they're not trying to be annoying. Indeed, they were otherwise polite and well-behaved.
