Literally, no transportation in Hong Kong can literally beat Mass Transit Railway (MTR) as the easiest way reaching Disneyland unless you hire a taxi service!
Citybus & NWFB offer their bus service to customers reaching Disneyland. You can access the information on their website. One thing want to mention here is Bus No. R8. This bus will take you to Inspiration Lake Recreation Centre from Disneyland. Please check with Help Centre in the amusement park or shoot them an email beforehand.
There are three hotels available for you to choose from in accordance with the theme you like. They are Hong Kong Disney Hotel, Disney Explorers Lodge and Disney's Hollywood Hotel. There is a complementary shuttle bus service provided as mentioned above.
Hong Kong Disneyland Resort Pier is a beautiful place to visit! Inspiration Lake Recreation Centre is another great place to visit if you have time. Please check with Help Centre in the amusement park or shoot them an email.
Unless you want to travel back and forth in town. Disneyland is the only provider of food and drink in the park. Unfortunately, I can't find any alcoholic drinks in this park even I made my very best attempt but failed the mission!
