TRANSPORT
SONG THAEW - the red jump on/off taxi's; you can pull them over, for 30THB per person they will bring you all around the old town; airport, trainstation or busstation will be likely 150THBTUK TUK - you pay for the experience/fun, not for the transport - always more expensive, but negotiating can be useful. 100-200THB to get anywhere
GRAB and BOLT - essential: get GRAB or BOLT app on your phone. BOLT is cheaper than GRAB. Works very good in Chiang Mai
