The Bluebirds face Sheffield Wednesday knowing that a point would be enough to secure a place in the Championship play-offs.
And Jones believes his side is prepared for the occasion.
"It's a big occasion for the club and an opportunity to be where they've never been before," he told the club's official website.
"We've been building for the last 18 months to try and get there and we've done well.
"We're going to bring a lot of supporters and I believe it will be Sheffield Wednesday's biggest crowd of the season. So it's got all the ingredients of a good game, but we know what we have to do."
