As many unofficial Olympic projects had to close early - London Pleasure Gardens - or didn't open - Scipmylo Festival - The Ultimate Experience used the Games to create houses that proved popular with both domestic and overseas guests in the capital during the Olympic period.
Famous guests at the venues included Carl Lewis, Dick Fosbury, Kayla Harrison, Jessica Fox, Tommy Gossland, Conlin McCabe and the New Zealand football team.
Stephen Lawrence, managing director for The Ultimate Experience, said: "It was great to see two of our most popular Christmas party venues put to such great use during the Games. For many who could not get tickets for the events it proved to be the next best thing to being there.
"The two venues appealed to slightly different markets, with the Tower offering a slightly higher-end hospitality opportunity, and the Camden Centre appealing to the younger crowd as it changed into a night club following the big screen action."
The programme kicked-off with a seated dinner at the Tower of London venue, which attracted more than 600 guests and was hosted by Olympian and BBC swimming commentator Mark Foster.
Afterwards, both venues were converted into a more informal club format where guests could enjoy hospitality from Create and Touch of Taste.
