Get around:
Apart from a handful of privately operated examples, Pattaya has no tuk-tuks and most ad hoc local transport is undertaken by a flotilla of over 700 dark blue colored songthaews - pickup trucks converted to buses, also called Baht Buses. The official "bus" fare is 5 baht for trips within Pattaya, however foreigners are universally expected to pay 10 baht. Having the correct change is by no means essential, but does keep the potential hassle factor to a minimum. Flat fares only apply when operating as a bus; beware the driver of an otherwise empty songthaew, especially one that's parked up at the roadside, who might presume (or decide on your behalf) that you want to charter - in which case expect a much higher fare of 100 baht or more, depending on your negotiating skills.
