I was there in april 2014 - and i have to say that it was totally great!!!!
The park wasn't really full, the first 3 hours were so empty that i didn't had to queue. We haven't eaten there but there is nearly just asian food.
Admission costs HK$450 (makes 45€)
If you are arriving at the airport, buy your tickets there - there are two lovely shops! That saves time when you go to the park.
And there (and also in HKDL) are many special offers (or they have been there when i was there) - e.g. buy 3, get 50% or buy 4 and get 70%.
-Grizzly Gulch: this rollercoaster is SO great! It runs so smooth and calm, but it is fast at the same time. Don't watch a video before, you will be very surprised!!!
-Mystic Manor: SO great, too. Its a trackless attraction with a cute little monkey who opens a forbidden jukebox. This juke box turns everything inside the mansion alive.
-Mickey's PhilharMagic: Great show, maybe you know it. Just two words: smell & sound.
-The Many Adventures of Winnie the Pooh: Pooh's funny honey hunt.
-Space Mountain: rollercoaster without loops
Ride Grizzly Gulch and Mystic Manor as often as you can early in the morning. Use the Single Rider Line for Grizzly Gulch.
All that i wrote may be a bit mixed up but i hope i could help you. If you have any other questions, tell me
