Thanks Blair, for the warning. Having seen it, it occurred to me that it might be cheaper to shop around for the cheapest single crossing on the selected day and just use the return half of Speedferries. However, having just today returned by Fastferry hydrofoil, that would not work as you only get the return ticket when you book in at Dover! In our haste to get a cheap crossing in school hols, we booked with Speedferries for morning of Sat 7th August and later realise that is THE day to avoid! (The 1st day of French hols) Not sure if I can face trying to change it for Sunday. Maz
