It's not necessary to have a car in Edinburgh, as the city is quite walkable and has an extensive and efficient public transport system. Driving in Edinburgh has its quirks and pitfalls—particularly at the height of festival season. Metered parking in the city center is scarce and expensive, and the local traffic wardens are an unforgiving lot. Note that illegally parked cars are routinely towed away, and getting your car back will be expensive. After 6 pm, the parking situation improves considerably, and you may manage to find a space quite near your hotel, even downtown. If you park on a yellow line or in a resident's parking bay, be prepared to move your car by 8 the following morning. Parking lots are clearly signposted; overnight parking is expensive and not always permitted.
