RKV is the city airport, distinct from KEF. Allow a separately planned transfer if your flights use both airports.
Confirm the supplier’s exact city-airport branch and terminal meeting arrangement in writing. A Reykjavík city office or KEF branch is not automatically a collection at RKV.
A car can link rural accommodation and sights beyond scheduled public transport, but it also makes you responsible for weather-led decisions. A guided excursion can be a better fit if you do not want to drive in unfamiliar winter conditions.
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.
