Just had three good weeks in Tortosa and checked at the Reus Airport Information on  the day of return to UK as to how long I could leave my car at the Carpark, and was told that there was no limit if you left it in the "Provisional Carpark" because there is a lot of work going on in front of the Airport buildings. So I did, it will be interesting to see if it's still there in January and all in one piece after two months!! We can but hope!!
