We are going to Costa Del Sol for our holiday and will be leaving these 2 car seats behind.  I have bought them brand new and used for one week in Portugal and to be used for one week in Spain.  It is a waste to leave behind but our kids would have grown out of them come our holiday next year.  It would not be worth taking back to the UK.  If anyone knows someone who may be interested, please let me know.  They must pick up at specific time and date at the airport when we leave.
