Hong Kong Disneyland has the FASTPASS system, though only at three attractions. You can obtain a pass, then come back at the specified time and enter through a special queue for a "minimal wait in line." There is no additional charge for this.
There is the option of a VIP "Disney Spectacular Tour." This is quite expensive indeed: HKD$5,688 for three hours for up to six people (+ $1,600/hour after that), plus park admission. You'll get a personal guide who will show you around the park, including "direct entrance to rides of your choosing."
