We were disappointed with HK Disneyland. The train wasn't running and the Castle was under renovation, as were several other areas. It had an air of dilapidation. Our coach driver advised us to take food in, not in our bags, which would be searched, but in our pockets. The reason for this was that They want to make you pay the incredibly high prices for food they sell. He also suggested not buying souvenirs there, but taking a picture, then getting the item from Ali Baba (or Ali Express I suppose). A basic souvenir mug cost A$20 approx, and watches were about A$80. The parade though, was fantastic, and made up a lot for the rest of it. It's on twice a day, in the afternoon and evening. The fireworks that we'd previously seen there were suspended for a while, due to the renovations. An MTR station is right there at the gates   change at Central for other lines. There's also a ferry but it limits you to certain times of leaving, so MTR, taxi or bus is better. For a senior, HK$2 on the Oyster Seniors card gets you all the way back to a station close to your hotel, so don't bother with a tour.
