how to take taxi from HK airport to gold coast hotel castle peak bay for 4 adults and how much?

Hi, Andi, you can follow the signs and take the down-ramp on the left when you get out of the Arrivals Hall to get to the taxi stand. Separate aisles are designated for different taxis. You can choose the red or green taxis. 4 people can sit in one taxi and it costs about HKD200-220.
