I used this airport (from/to LGW with Easyjet) and found it great however,.....I was there on business with Companies, whom are all based on the Asian side. The taxi took only about 20-25 mins from SG to the Marriott Asia where I was staying. However, I concur, the city traffic is horrendous and the best way to get to the European side is by Ferry from say, Kardicoy, then walk or tram it.
