Thanks for all the new advice, much appreciated.
I have been warned by some that Tangier is not a good place to leave an a/c for a few days. I must admit I'm surprised that a reasonably sized international airport is not up to this? Can anyone shed any more light on this? I'd consider ending the flying in Spain/Gib and getting the ferry over if it really is that bad, but it's hard to know - never landed there.
