The cheapest way is to walk about 15 minutes to TST MTR station from the hotel first and then take MTR to Disneyland, need to transfer at Lai King and Sunny Bay. The costs is 18.5HKD. No direct bus running from the hotel to Disneyland but there are direct bus (R11) from Disneyland after the firework show at night back to Kowloon. So, if you want to take bus from Ramada Kowloon to Disneyland, take bus A21 to Lantau Link Toll Plaza first, then change to bus R8 to Disneyland. The costs is 33HKD plus 7HKD, in total 40HKD. BUs R11 costs 38HKD. So, also cheaper to take MTR back to Kowloon from Disneyland.
