Here's teh deal...hiring a car with Hertz from Barcelona airport and I have booked a child seat (booster seat/highback). They are going to charge me nearly £60.
We are travelling with Easyjet so pay for any luggage we put in the hold...but to pay for an extra 20kg it will cost us £18. So if I stick her current booster in a holdall and put it in the hold it will cost us £18 (and as it doesn't actually weight 20kg will give us extra luggage allowance which we could use for clothes etc).
Is this a stupid idea? The only downside I can think of is the risk of holdall with booster in getting thrown about in the handling and damaging the seat? Other than that it all seems like pluses and we know exactly the condition of the seat we will be using.
I have alos already booked my car but I think that the cancellation policy will allow me to make changes without charge.
