Hi, firstly good luck with the brakes and Mot for next week. The ferry costs should be about 200 euros on an open return, we paid 220 and went from Algerceiras to port Tanger Med which we were advised is much quicker and less agro once arriving Morocco. Tickets you can buy on arrival at Palmones through Viajes Normandie, Juan Carlos very helpful guy. Campsites are pretty cheap over there anything from about 5-10 Euros a day depending, but generally a bit basic standards. We stayed mainly on them as they are cheap and at least then you can leave motorhome to go and explore towns ,also I like to have a few beers, G&T’s etc. So at least you know you’re not going to get moved on after having a few !!
Fuel is pretty cheap too about €1 per litre for diesel and food in supermarkets similar to here in Portugal, we found the big Supermarkets like Carrafour and Marjine were more expensive but you can get pretty much anything. To eat out though is quite cheap we found. Enjoy..
