The Ladies senior football All-Ireland finals have been played at Croke Park since 1986 but this Sunday will be the first time the semi-finals have also been staged at GAA HQ.
Bríd Stack, who won 11 All-Ireland medals with Cork, told RTÉ Sport that the change is "an absolutely huge move forward for Ladies football.
"They've been extremely progressive in their thinking in the last few years, securing big sponsorships, so it doesn't really surprise me that they've gone for the jugular and decided to have the two semi-finals at such a big venue.
"It does need a massive attendance, Croke Park is a very big stadium. They are hoping to get a crowd of around 10,000-12,000 but you would be hoping a lot more would turn up on the day.
"There are going to be two quality games on display so you would hope people will put their money where their mouth is and get out and support their counties."
Bríd Stack's All-Ireland semi-final verdicts
Cork v Dublin, Croke Park, 3.45pm
Three-in-a-row chasers Dublin and Cork have met in four of the last five finals, including last year, and one of the counties has been in every single decider since Mayo beat Monaghan in 2002.
That's not possible this time and Stack has a sneaking suspicion her native county might be the ones to grab the final spot.
"Both teams have racked up huge margins in the Championship this year, and have possibly come through relatively untested, barring the Armagh game for Cork (a one-point defeat) and the Kerry game for Dublin," she said.
"Cork have been playing lovely football. The Armagh game was one they went into knowing they were already qualified but they still won't be happy with a lacklustre performance.
"Dublin took about 40 minutes to break down Kerry in the quarter-final but, as they do, they kicked on and were a different team in the second half. There's a real ruthlessness in this Dublin team, Sinead Aherne was immense on the day, scoring 2-05.
"My one reservation about this Cork team would be that they are conceding a lot of goals, 10-21 in the last three games. You can't be giving Dublin, who are just poachers for goals, an opportunity to put you away.
"Cork have beaten Dublin twice already this year, albeit in the League but it was probably a hoodoo for a lot of young girls on the team who hadn't beaten Dublin.
"I would give a very tentative nod to Cork. But Hawk-Eye is going to be in operation as well and given only the minimum has separated these teams in recent years it could come into use."
Mayo v Galway, Croke Park, 2pm
The other semi-final is a rematch of the Connacht final, which Galway won by seven points.
The Tribeswomen beat Waterford in the quarters to get here while Mayo got the better of Armagh.
"It's a very hard game to call," said Stack. "Mayo have made huge strides in the last year and a half and probably all against all odds are now in an All-Ireland semi-final.
"There's a real fight about this Mayo team. They have lovely footballers and they are dogged and so tough.
"The Connacht final was played in absolutely horrendous weather and went to a draw but Galway probably learned a bit more on that day and really kicked on the second day.
"I tipped Galway at the start of the year as being a team to watch. They have dug out games during the Championship, which will really stand to them.
"They do have to get over the hoodoo of being a team noted as not performing on the big day. This is their first day playing at Croke Park since 2005.
"(Manager) Tim Rabitt has been a revelation for them and has instilled real confidence.
"It's a huge opportunity for them to go a step farther after the semi-final last year but it will be a ding-dong battle between the neighbours."
