cost for three adults to get the limousine service from Hong Kong Intl airport to Shenzhen

Generally speaking, the price is around 180 HK$ per adult for the limousine. For kids under 12 years old, the ticket price is about 120 HK$.

Hi Lyn, save your money and get the train. heaps easier. also you will have to get visas at the train station from memory when you see the customs officer, turn around and there should be a set of stairs, go up them and get you visa then proceed thru the customs turnstiles. this is also the same train you catch to disneyland if you are interested.
have fun cheers Matt
