Not something I book often, but useful when the forecast is bad or I've got an early flight and don't want a bumpy ride.
Same driver-included setup as the rest — just a sealed, air-conditioned car instead of an open tuk-tuk.
Costs a bit more than the tuk-tuk for the same route, but the AC and closed windows are worth it in a downpour, and it's the one I'd pick for an airport run.
Same rule applies — agree the fare before getting in, there's no meter.
