There is a (I believe it's the ONLY) "bo mo" bus company called "Choi Yue". She provides bus services mainly for 加州 and 綿繡 kids who go to Kln Tong. Last year, the monthly bus fee is $1600 for round trip. The bus takes "route 3" (i.e. Tai Lam Tunnel) and the travel time is about 1 hour to 1 hour 15 minutes. You can get on the bus with your kids for the 1st one to two days (free). As I lost her phone number, pls see if you can check 1083. Otherwise, I'll see if my 綿繡 friends know.
