Thanks PhilandMena sounds straight forward if not a tad cavalier...You will need a green card from your insurance provider which will give you up to 3 months legal entry into Maroc. (Third party cover only, but check with your provider as it may not even cover that ? It's just a legal document that is required by some countries outside Europe). Home insurance ! Talk to them and see what cover you have and then extend cover for duration of trip. (I'm with Aviva, I get 60 days cover free then 10% of total policy price for every additional month after that. Policy holder must return to house before the period starts again and I must have someone (neighbour) clearing mail doing visual check weekly).
Travel insurance, we use EHC for Europe but take out medical cover for Moroc. (This means in effect taking out travel insurance for whole trip. We tend to get a reasonable one then strip everything out except the medical cover. Make sure they have a manned 24hr telephone service. (Which will cost you an arm and a leg if calling from Maroc, so plenty of credit on the phone.)
I factored in all these costs, including ferry and additional fuel, campsite costs etc and still made quite a saving compared to Spain alone over 3 months. The longer the stay the bigger the saving.
