Not long got off ferry from St Malo to Portsmouth which takes 9 hours.
Most of the daily entertainment is in the bar such a family quiz panto ect.
There aren't many foot passengers it's mainly cars caravans & motorhomes so lots of the people on board were going to be driving once we arrived back at Portsmouth but a huge amount of people were sat with pints or glasses of wine 
There were to couples sat next to us we saw them consume at least 3 alcoholic drinks. When the announcement came on about who leaves to go to which deck to get their vehicles when we dock deck 3 was announced first so this is mainly caravans motorhome and larger vehicles i then hear the couple's next to us say well thats us then.
We couldn't believe they consumed so much alcohol with a good chance they'd be towing a caravan.
A lot of others were also drinking though definitely more than one drink too. My DH pointed it out at lunch time the amount of alcohol being drank so throughout the afternoon we did some people watching and it was quite shocking.
breath testing should take place at the docks before people head off onto the road.
(I'm not moaning because i didn't get to have a drink
genuinely just shocked)
