To the Gulf islands
Don Sak, in Surat Thani province, is the mainland pier for the ferries to Koh Samui and Koh Phangan. Chumphon's Lomprayah pier is where the high-speed boats leave for Koh Tao. The car takes you to the pier; the ferry ticket is bought from the ferry company.
Stops on long drives
Short stops for food, fuel or the toilet are fine. A sightseeing stop or a detour is priced by message before the trip.
Phuket to Bangkok by road
Phuket to Bangkok is a full day's drive — about 840 km and 11–12 hours. Flying is usually faster and cheaper; the car makes sense for groups with a lot of luggage. The fare is to (and from) Phuket Airport: for a hotel elsewhere on Phuket, that beach's fare from the airport is added.
Also on request
Trang and Satun piers (Pak Meng, Pak Bara for Koh Lipe), Khanom and Hat Yai: send the pickup and destination on WhatsApp for a fixed price.
