Will the unlimited MTR rodes for the next 3 days include ride fom Kowloon to Disneyland Line?

Yes, you can ride free from Kowloon to Disneyland. Remember that you can ride free on all MTR lines(except Airport Express, East Rail Line First Class, Lo Wu and Lok Ma Chau stations) within 72 hours after swiping for the first time at the entrance gate. Have a nice trip! :)
