The week of the Lunar New Year is the busiest of the year. I've been monitoring both HK and Shanghai wait times. in Shanghai, 7DMT go up to 150 mins, Soaring go up to 180 minutes, Tron to 135, Pirates to 75. in Hong Kong, Pooh and Space Mountain go up to 70 minutes, Big Grizzly and Mystic Manor to 45.
The following week, crowd should ease up as the public holiday would be over.
