Dave, You can stay in Cadiz for 3€ for every 24hrs in a secure car park right next to where the cruse ships come in. We went looking for street parking and the place was rammed so I tried to enter the port directly and was told this is for passengers only (LOL) but got talking to the plod who told me where I could park and there are plenty of places. Bit tight getting in as you have to make a hard right turn so best to make a sort of three point turn getting into entrance, collect tickjet and pay at office not machine when leaving to get the discount. There are toilets there too.Like it. @PhilandMena Are you Cadiz area we'll be round there Monday or Tuesday for a few days stopping at the acsi site at Puerto de Santa marie, meeting Maggie's brother off a cruise ship in Cadiz Thursday
