just a word of advice if you are heading for the centre routier at bezier, there is no restaurant, and the van that used to come round in the evenings doesnt anymore, so the only food on offer is in the garage (so thats nice and cheap 
), and the showers are currently broken, the only things it has to offer is secure parking you pay for and free internet
far better off to head for Narbonne, only 20 minutes towards Spain and there is a choice of truckstops on the one ZI 
or the chap told me on the way back, you could drop your trailer in there and 6km down the road is the beach and restaurants! wish i had known that before i parked and called it a day!
If you are going to park up near Narbonne, the routier on the N13 before you come to Narbonne is pretty good and it is open at the weekend, including Sunday’s

wouldn’t that be the N9? the N13 is further north isn’t it? on the ZI there’s 2 routiers, one has its own parking operated by a ticket and barrier system although the walls are not tall but its pretty secure
