The events wing at Center Parcs' new Woburn Forest site will cater for up to 800 delegates in a theatre-style setting and 680 delegates for a gala dinner.
It will also offer an array of indoor and outdoor team building and incentives packages.
The new meetings and events wing accompanies the site's 75-bedroom hotel and 625 luxury forest lodges.
Daniel Whittemore, head of corporate sales for Center Parcs, said: "We are extremely excited ahead of the opening of our brand new venue.
"We are eager to introduce the facilities to current and potential clients who have not had the experience of having held meetings and events with Center Parcs."
Woburn Forest is Center Parcs’ closest site to London, which is less than an hour away by road, rail and air links.
