Nope. HKDL is like 'Disney light'. From what I've heard, even when it's crowded, it doesn't compare to the US or Tokyo parks. You'll struggle to find ANY line that's more than an hour long. On a Saturday afternoon in March (not peak season, but definitely a popular time of day) we walked up to the parade route about 10 minutes before it started and got a spot on the curb, then walked on to Buzz Lightyear, waited 10 minutes for Space Mountain, and 5 minutes for Big Grizzly Mountain. There was a 30 minute wait for Mystic Manor so we gave it a miss. The rides in Toy Story Land will generally have longer waits than the rest of the park as those rides are slow loading.
FWIW the park was practically empty until lunch time, and the crowds built up pretty gradually from then. And when I say practically empty, I mean all the rides were walk ons and it would have been easy to get photos with not a single other person in them if I'd had my camera.
