Marylebone Christmas Lights
Time Out says
This Christmas lights switch-on ceremony on one of London's most atmospheric high streets is not to be missed. Alongside the lights, there are stalls to browse, a snazzy tombola and a decent celeb to push the button. The lights are usually on display until Twelfth Night.
The 2018 switch-on takes place on Wed Nov 14. Activities will run from 3pm-7pm, with the lights coming on at 6pm.
