Child car seats
Keeping the kids safe while driving is one those holiday essential items that you need to plan for in advance. Remember that when you book car seats with your hire car most companies state that it is a provisional booking subject to availability so you may not get exactly what you think you have booked. It's also important to factor in the cost as some hire companies charge more than it would cost to buy a new seat.
So what are the options?
Hire car seats with the car but book in advance as the car hire cost will be cheaper and they will reserve a seat for you. There are mixed reports about how good the seats are and many companies will not fit them for you. To make sure your child is safe check the structure of the seat under the outer fabric, make sure the seatbelt and the straps are not twisted and ensure the locking mechanism is secure. If the seat is not secure in the seatbelt get help from the hire company. This option can be eyewateringly expensive for longer hires as some companies charge per day.
Take your own seat with you - this sounds more of a hassle than it actually is and will often be free! It also has the benefit of your seat being familiar to you and you can use it in a taxi to the airport. Many airlines let you take car seats free of charge - here is a handy link which lists popular UK airlines and their rules on luggage (including car seats & pushchairs) for children and babies.
