I was checking the app on Dec 25. Mystic Manor peaked at 45 minutes. Big Grizzly Mountain and Hyperspace Mountain peaked at 60 minutes. The longest queues were RC Racer and Parachute Drop which peaked at 70 minutes.
I went on Dec 26, none of the rides went above 40 minutes the whole day. I know Tokyo Disneyland is objectively better but during high season like this, I'd rather be in Hong Kong Disneyland.
