I swear this forum has denigrated into a cesspool of cynicism and misinformation by the few usual suspects.
The guy doesn't know anything about KM, he is only going off of what his parents said, can't we just take it at face value without making snide remarks? Stop being a troll and an ass.
As to transportation, it is not that big of a deal Cat, a hassle, but no big deal. Once you exit the airport there any many airport shuttle routes that goes into different parts of the city. The trick would be which bus you need to get on and what stop to get off, especially if you don't speak Chinese, the fare is ¥25, approx 4USD. Failing at that, there will be many people that will approach you as you exit the airport to ask you if you need a ride. Having never used their service, it is between ¥100-¥200 depending on where you are going and your negotiation skills. The last option would be to take the subway to the end of the line (don't worry, there is only one subway leaving the airport to the city and there is only one stop total, you can't get lost). The subway will leave you at the eastern edge of the city, from there you can either take a taxi or a bus if you are so inclined.
I would say if you really want to surprise your parents, transportation difficulties should not be a good reason to stop you. Unless maybe your parents have other *reasons* for dissuading you?
Hope this helps
Cheers~
