Did you really say a taxi is 70p from Sousse to the PEK Marina. I started going to PEK and Sousse in 2003 and taxi cost between £3 and £5 then. No way is a taxi less than 2 dinars.
Just back from here. The place is very run down compared to what it used to be like. Also the usual annoying harassment from the shopkeepers and boat owners....
