The announcement that Scott Bemand's side will return to the Aviva Stadium to play World champions England in May 2027 has fans rushing to take advantage of the early bird ticket offer.
A record crowd of 31,294 turned out to watch the first ever Ireland Women's standalone fixture at the home of Irish Rugby, when they overwhelmed Scotland 54-5 on the final day of last season's Six Nations.
There will be a serious push to take that attendance figure as close as possible to a sell-out, as Dannah O'Brien and her team-mates are set to ride the Green Wave back to the Aviva on Saturday, May 8 (kick-off 2.45pm).

It will be the penultimate round of the Championship, and with England sure to draw thousands of their own fans to Dublin, and the inaugural British & Irish Lions Women's tour happening just a few months later, it promises to be a massive occasion.
Giving her reaction, Ireland star O'Brien said: "Yeah, it's really exciting news. I think we're going to look forward massively to that one as a group.
"It was great to play our last Six Nations game against Scotland at the Aviva Stadium, and we had, like, a really good day out for us.
"So, hopefully we can attract another really big crowd there, and yeah, it's definitely a fixture to look forward to."
Just 22 at the time of the historic Scotland game, the Tullow native looked right at home on the Aviva's pristine pitch, missing only one of her eight conversions and playing a crucial role in a dominant first-half display.
She got a taste for performing in front of large attendances during last year's Rugby World Cup in England, with three of Ireland's matches attracting five-figure crowds, including over 30,000 for the clash with New Zealand in Brighton.
O'Brien's first World Cup experience, and the fact that she has lined out against England twice at Twickenham Stadium in recent years, has only whetted her appetite for more big days in cauldron-like atmospheres.
With more people than ever turning out in support of the Ireland Women, the squad's continued growth under Bemand has been reflected not just in their results on the pitch, but those rapidly increasing attendances.
It was back in the 2019 Six Nations that Ireland and England drew then-record home crowds of 4,637 and 4,674 for standalone Tests, respectively. Roll on seven years, and those figures have been utterly dwarfed by both nations.
England won the World Cup on home soil, watched by 81,885 fans at Allianz Stadium, and set a new Six Nations attendance record of 77,120 when they played Ireland in Twickenham last April.
Similarly to the Red Roses, Ireland have held their home games at multiple venues in the last few years, reaching all four provinces. As part of their Women's Strategy, the IRFU showed their commitment to growing the Green Wave further by staging the team's 2026 Six Nations finale at the Aviva.
O'Brien has been really encouraged to see the number of Unions that are backing their Women's sides and deservedly giving them centre stage at their national stadiums.
Such has been the increading clamour for tickets, a new Women's Six Nations attendance record was set just three rounds into last season's tournament, with a cumulative crowd of 194,466 spectators.
Just like Ireland and England, Wales and Scotland also played at their national grounds of the Principality Stadium and Scottish Gas Murrayfield, respectively, last spring. The Scots broke the 30,000 mark for the visit of the Red Roses.
"I think it is becoming more common now in the Women's game. It's great to have standalone fixtures for us in the Aviva, like it's the home of Irish Rugby," admitted the young out-half from Carlow.
"It is great that we're building crowds and hopefully we can sell out the Aviva soon, in the next couple of years.
"That is where we want to be, and we're just really happy to be playing big fixtures like those on a regular basis.
"As a group, we are ready to go there. We're ready to play these big occasions, and that's what we need kind of building into the next World Cup as well."
While Scotland have decided to return the favour and put on next year's Six Nations opener against Ireland at Murrayfield, the girls in green will be back in Galway the following week to face France.
They have a proud winning record at Dexcom Stadium, having beaten Italy 57-20 there in mid-April, and held off Japan for a 31-24 victory just last week. Galway's own Béibhinn Parsons scored five tries across both games.
The Italy encounter brought a crowd of 9,206 to the home of Connacht Rugby - a new Ireland Women's record at the time - and their April 17 date with les Bleues is sure to have a high demand for tickets.
O'Brien agreed: "France is definitely another special game to look forward to. Last year there was a massive crowd in Galway against Italy, and again we put out another good performance there.
"It's a lot easier to play when you have an Irish crowd behind you, so yeah, hopefully we'll do the same next year."
Leaving her thoughts of the 2027 Six Nations to one side, the Old Belvedere clubwoman's sole focus this week is on making it back-to-back wins against Japan.
Ireland and the Sakura Fifteen will face off again in Cork on Saturday (kick-off 2pm - live on IrishRugby+). This Test at Virgin Media Park is outside the WXV Global Series window, with tickets available to buy here.
Head coach Bemand may opt to blood more new players - Jemima Adams Verling and Beth Buttimer made their debuts in the last two weeks - but whatever the selection, O'Brien wants the performance levels to rise ahead of their tour to South Africa.
"We were delighted to get the win. I think we're building into this campaign nicely. Kind of had a slow start against the USA.
"But to get the result last week we were really happy, and I think we can step up another few gears this weekend, and hopefully have a better performance again.
"I think with the six-day turnaround, you have to compress the week a bit. It is handy that we are playing against the same opposition, so we kind of know what areas we're going after.
"If we can go after another performance and hopefully secure another win, like that's massive for us, building momentum to go away to South Africa which will be a challenge for us," she added.
