First of all, go only during weekdays. Again, avoid weekend. And to be triple sure, go during weekend, and mainland china holiday season at your own risk.
We travelled specifically on a Tuesday, as our neighbor who travelled there during weekend, three weeks before us, had such unfortunate encounters. They waited for 2 hrs for each ride, shoved around and cut q by all other people... Comparatively, our average q time is 2 mins for each station, and the longest one is the character photo taking session at fantasy land, max 15 mins for Mickey mouse. During weekdays, china mainland tourist are rare, as such not so much jumping the q, or rushing in and pushing you out of the front q (not that it doesnt occur, just fewer).
IMO Disneyland hong kong did their best, but there is a limit on how they can control the crowd.
Back to the fun part: yes both my kids enjoyed the trip totally, highlight of their Hk trip.(aged 3 and 4). I would suggest upon arrival take the train for one stop to fantasy land, cover all scenes there (the little world is nice, also character photo in the park). The self driven car at toy story land is very nice, and the LILO and stitch live q&a session is funny. Parade is grand. I find the lion king performance also a must to enjoy. Ending the park visit with the highlight Of 8pm fireworks.
We stayed at Disneyland hotel for that night but IMO ~400usd is a hefty price tag for the hotel. You are better off getting a good hotel nearby and take a cab or mtr after exiting the park.
A must visit, especially for kids. Food is pricey but within acceptable range.
