Twice been to Hong Kong and had to go to Disney both times obviously. We stayed in Kowloon and as noted the MTR is so easy to navigate to Disney. If you are doing things in Hong Kong the next day and are up and about early you could do as we did and buy the Tourist Day Pass for HK$55 which got us from Kowloon to Disney and back and allowed us travel the next morning as it has a 24 hour expiry date from the time of the first use leaving only a single journey ticket to buy for our trip home the next day.
We also bought our tickets via expedia (not sure if that is available in the states but does in the UK). We picked them up for £37 each (about US$60). We picked up our using the voucher with no problems.
We also arrived way too early for entrance to the park. They open at 10am.
The rides were fine. The castle was a direct lift from Anaheim. The park felt different. I didn't think Main Street worked in Hong Kong. The locals live in high rises that are very very high and cubby hole sized. It doesn't compare to the Victorian era Main Street. Nostalgia for American old times in Hong Kong is awfully strange. There is no history of pining for those times. Perhaps a British themed version might work better? British Hong Kong is the major influence there, not America.
Overall, the trip was instructive. It felt like home at times. The park layout is very much the Anaheim copy. I'm just disappointed that when I walked out, there's no 5 Freeway.
@Stephen and Anon - thanks for sharing your experiences. (And good tip on the Tourist Day Pass!)
In regards to Main Street, at think at this point it's more about Walt's nostalgia than our own. In 2013, how many visitors at the U.S. parks have memories of that era? Regardless of place, Main Street is a Disney parks tradition, found not just in Hong Kong, but also Paris and Tokyo (where it's called World Bazaar, but shares the Main Street aesthetic). Maybe I'm too much of a purist, but I can't imagine a Magic Kingdom-style park without it.
I'm planning to visit HKDL on 27 Dec with my family. Shall I buy one day or 2 days pass?
