Went over on Thursday with Number One Son as he wanted some wine; I wanted to cut the grass; and we both fancied a boy's day out and a decent lunch.
First time on Speedferries: not an auspicious choice as the Manche was a tad rough! At one point I did think the damned thing was going to tip over!
Price was excellent £23 for the return trip: 07.00AM sailing out and the 05.00 PM sailing back.
Passports were checked both ends: in the case of the return journey, twice: once by the Police aux Frontiere and then again at check in with Speedferries.
On Eurotunnel which Mrs G and I use frequently, passports are checked once only on entering the port restricted area.
UK Customs of course, in Coquelle are amalgamated with Immigration. Never been stopped.
On all ferries, I have always had to drive through the custom's shed at Dover and have rarely been stopped.
Coming back from France last year again with son on a wine shopping exercise, we were stopped strangely enough by French customs, who looked inside his Terrano with amazement at the sheer quantity of wine, laughed soundly, asked a couple of questions (we explained that some was mine but the bulk was son's annual supply!) and waved us on.
"Yes, but that apart, Mrs Lincoln, did you enjoy the play?"
