Family car hire on the Costa del Sol and what to check before you book

(Marbella, Spain)

Family car hire on the Costa del Sol goes smoothly when three things are sorted before you land. Every child under 135 centimetres has the right seat, the pick-up suits a tired family and you know what the insurance leaves out.

Plenty of families are doing it. Aena counted 2,805,764 passengers at Málaga-Costa del Sol airport in September 2026, and the United Kingdom was the largest foreign market with 670,319 of them. A fair share of those arrivals walk out with a buggy, two suitcases and children who stopped being patient somewhere over France.

Child seats are where most families get caught out

When Which? asked 1,800 British parents about hiring a car seat abroad, 85 per cent said something had gone wrong at collection. A third were given no fitting instructions, almost a quarter received a seat that did not suit their child, one in five found no seat in the car at all and 14 per cent spotted visible damage. More than half used the seat anyway because there was nothing else on offer.

Those figures come from 2020, but the advice that came with them has not aged. Give the height and weight of each child when you book, not just the age, and ask for a high-back booster rather than a backless cushion. Fit the seat yourself before you leave the car park, while someone from the desk is still close by. Run the straps through your fingers, look over the shell for cracks and check whether it fixes with the car belt or an Isofix base. If anything is missing or broken, ask for another one there and then.

Some parents skip the problem altogether. easyJet and Jet2 carry a child car seat free in the hold on top of the normal allowance, and a seat you already know how to fit is worth the extra minutes at bag drop. Other airlines set different limits, so check yours before you pack.

What Spanish law asks for

Spain requires a child restraint system for every child up to 135 centimetres tall. The DGT, the national traffic authority, says to choose it by weight and height rather than age, and as a general rule it goes in the rear seats. A rear-facing seat must never sit in front of an active airbag.

By weight, a baby seat in group 0+ takes children up to 13 kg facing backwards. Group I covers 9 to 18 kg with a five-point harness, and groups II and III, from 15 to 36 kg, lift the child until the adult belt crosses the shoulder and hips in the right place. Since 1 January 2026 the V16 warning light has been the only legal breakdown signal in Spain, replacing the old triangles, so it is worth asking where it is kept before you set off.

Airport pick-up with tired children

After a flight with small children, the walk to the car matters more than the price difference between two companies. Some firms hand over the keys in the terminal car park, while others send you on a shuttle bus to an office outside the airport, which means another wait and another transfer with luggage and a sleeping toddler. Ask which one you are booking, whether they track your flight and how long they wait if it lands late.

The boot deserves the same attention. Two suitcases and a folded buggy fit in a compact only until the child seats go in, because a seat takes a good part of the back bench. With three children or a lot of luggage, a seven-seater is usually the calmer choice. Tell the company how many cases you are bringing, then load everything into the boot at collection before you sign.

The small print that costs families money

When the UK European Consumer Centre looked at car hire complaints, the same three causes kept coming top. Damage charges after the car had been returned, disputes over insurance and fuel policies that make you pay for a full tank and bring the car back empty.

Each one has a simple answer. Film a slow walk around the car at pick-up and again at drop-off, with the fuel gauge and the mileage in shot. Choose a full to full fuel policy. Read what the excess is and what the cover leaves out, because tyres, windows and the underside of the car are often excluded even on the top level. Luggage and personal belongings are rarely covered by the hire company, so a buggy or a seat brought from home belongs on your travel insurance.

Days out with children by car

Marbella itself works well without a car, as the town buses link the centre, Puerto Banús and San Pedro de Alcántara. The car earns its place on the days further afield.

Bioparc Fuengirola is under half an hour along the coast, an easy first outing while everyone settles in. Selwo Aventura, near Estepona, is around 40 minutes away, and children under one metre tall go in free. Ronda sits a little over an hour inland, up a mountain road that ends at the Puente Nuevo bridge over the gorge. The Caminito del Rey takes around an hour and a half to reach and only admits children from eight years old, with proof of age for anyone under eighteen.

Most of these trips start from the coast road, which is why many families book car hire in Marbella (https://wikirentacar.es/en/) for the days out and leave the rest of the week to the beach and the bus. Two or three days with a car, a seat that fits and a full tank often cover everything a family really wants to see.
