Liepāja is a western Latvia option only when a suitable current flight and confirmed rental handover are available for your dates. Compare Riga before committing.
The airport’s rental information is dated April 2020 and describes Sixt meet-and-greet without a counter. Treat this as historical guidance, not guaranteed current availability: reconfirm flights, supplier service and meeting arrangements before booking.
A car can connect Gauja National Park, rural guesthouses and the western coast. For Riga alone, compare public transport and a later collection. A Liepāja stay needs its own flight and handover checks rather than assumptions based on Riga.
Compare airport collection with a later collection if you start with a city stay. Include the transport to a different rental branch and any extra parking nights when comparing the total cost.
