The Cotswold Conference Centre in Worcestershire said that the Olympics has helped fuel a 55% increase in bookings, compared to the same time last year.
By the end of June, bookings were up from £850,000 last year to more than £1.25m.
Operations manager Richard Howdle said: "We've increased our number of bedrooms, invested in a new dining room and won a series of fantastic awards so we are certainly doing our bit to improve our offer. However, there's no doubt that the Olympics is also having an impact by attracting business to the country.
"Our like-for-like sales have increased considerably, which I believe is due to the greater recognition we are getting, as well as the so-called 'Olympic effect'."
The Cotswold Conference Centre hosts events including a sushi teambuilding activity.
