From the website:

"ExploreGB is VisitBritain’s flagship event providing British & Irish tourism suppliers and destinations with an invaluable opportunity to meet and do business with over 200 hosted international travel buyers from 30+ countries. The event consists of two days of pre-scheduled 1-2-1 meetings with up to 50 meetings over the two days, based on both supplier and buyer preferences. It also includes networking opportunities including a cocktail reception and a gala dinner."

Sounds like a must-do event for tourism destinations and suppliers in the UK and Ireland.
