We visited Disneyland HK with our three kids   4,6, and 7. We did 90% of the rides attractions in one day! Yes it was tiring for the kids  rented a stroller for our youngest son but the older two walked the entire time. We were there from when it opened to about 5pm (nobody had the energy to stay any longer). Honestly my kids at this age could careless about the parade. The lines were not bad at all, the longest wait was probably 10 mins. DO get fast passes for Winnie the Pooh and Hyperspace mountain. You'd need to pre register for the Jedi training in advance (by hyperspace mountain and check the show times). Yes the rudeness of the mainlanders is not a myth....we've encountered a few pushes here and there to attempt to cut in front of us. Over all it is def doable to do everything in one day if you're an adult or coming with older children. Another note  my 4 yr old was tall enough to ride the hyperspace mountain but he DID NOT like the ride at all. Started crying in the middle of it (too dark fast). Would advise kids 5 and under to not ride this even if they are tall enough.
