I would recommend pre purchasing tickets online, showing up early, and going during the week and non school holiday periods to beat the crowds. If you're lucky to get a day where it's quiet, there are barely any lines which makes for a much better experience.It's one of the smaller Disneylands so you can definitely see most of it in one day. There are plenty of rides for all ages. Make sure you read the guide at the beginning of your day and plan your day well to see as many performances as you can.The food is terrible and overprice but that always happens with theme parks. Remember to pack some extra water and snacks to sustain you throughout the day. Make sure to bring lots of money because everything is so cute and you will probably end up buying lots of souvenirs.If you're going to Hong Kong then definitely set aside a day to visit Disneyland. You can't help but be happy when you hear the music they play throughout the place.
