Where to take blue bus? From hotel, facing main road, u turn left and walk all the way straight until u see a big circle with 4 intersection, continue walk straight to cross the 1st Zebra crossing, u see all blue bus park there. Ask bus attandance in blue top and bottom, he will tell u board which blue bus. All blue bus will show which place they going like BigC, Patong, Karon beach etc. Coming back, just ensure u take opposite direction or ask driver. To stop the bus, just wave, they stop for and u board. Bus can drop anyone on the way as long as within their driving route by pressing the bell.
