在普吉岛租摩托车划算，还是应该选择 Grab 和出租车？

It depends on your confidence and where you are staying. Phuket traffic and the hills can be intimidating and accidents are common, so if you are not an experienced rider, Grab and taxis are the safer choice for a two-week trip. If you do ride, always wear a helmet, make sure you have a licence that covers motorbikes and check your travel insurance covers it.
