If you have already been to Thailand, you know all about tuk-tuks (called tuk-tuks because of the sound they make, or so) and that they are a cheap form of transportation for short distances, not to mention a practical mode of transportation for weaving in and out the city. Tuk tuk is also popular means of transport in Luang Prabang and though you may not need it for transfer within this small town, it may be the best way to get to the surrounding areas.
