Transport for London has issued guidance to WTM London delegates ahead of planned DLR strikes on days two and three of the show next week.
TfL said: “No DLR services are expected to run on Tuesday 7 and Wednesday 8 November. Any services that do run are expected to start later and finish much earlier than normal.
“If travelling on these days, you should plan ahead, check before you travel, consider alternative routes and allow more time for your journey.
“Tube, London Overground, Elizabeth line, Bus and IFS Cloud Cable Car services are not on strike but may be busier than normal. London Trams services will also run as normal.”
TfL warned that services on the morning on Thursday 9 November may also have minor disruptions and advised people to check before they travel that morning.
It has advised people travelling to ExCeL for WTM on 7 and 8 November to use the Elizabeth line to get to Custom House or the IFS Cloud Cable Car services from North Greenwich to Royal Docks, which is about a 15-minute walk to ExCeL.
WTM London takes place from 6-8 November.
