London's Leicester Square will feature a warm and cosy looking bed as part of a message to remind festive revellers to get home safely.
The safety campaign urges partygoers to ensure they plan their trip home before they raise their first glass.
They will also launch a three-month trial of a marshalled mini-cab service out of Leicester Square.
The trial allows people to book and pay for a licensed mini-cab at the ticket booth and then be escorted to the taxi.
Councillor Daniel Astaire, of Westminster council, said: "We want people to enjoy themselves over the Christmas period but we also want them to be safe.
"Too many people head out for parties with no consideration about how they will get home at the end of the night."
British Transport Police Insp Kate Shaw said: "After a few drinks at the office party people are not as alert as they otherwise would be and this can put them in a vulnerable position. It's a simple tip that can save a lot of hassle - plan your route home before you start drinking."
The campaign includes posters on public transport and several free phone and text numbers for licensed cabs. There is also a number for train, tube and bus timetables to help people get home.
The marshalled mini-cab project was set up by merchants in and around Leicester Square along with local minicab firms, the police and the council.
It uses the London Information Centre in Leicester Square - the popular ticket booth - as its base and includes uniformed security staff to accompany people to licensed mini-cabs.
It will operate from 2200 to 0400 everyday and is aimed at steering people away from illegal mini-cabs that frequent the West End looking for fares and that have posed safety risks in the past.
Sarah Porter, representing local business, said: "We are trying to do everything we can to make travelling home from a night out in London's West End as easy and safe as possible. I think women in particular will appreciate this service."
