Some parking operators do offer longer-term parking with RingGo that may not necessarily be available using the on-site payment machines.
The maximum stay differs depending on where you are parking. Each location has different rules and regulations. The parking operators' signage in each car park or area will detail the various times available and the relative costs. Alternatively, you can search our Parking Locator which outlines full tariff information (both duration and cost) for each individual location.
