Leinster head coach Leo Cullen was delighted as his side spoiled Connacht's party, to record their 10th win in a row.
The defending URC champions pulled clear in the final quarter, as a try for Ciarán Frawley, against his future side, bagged a bonus-point win, and saw them pull clear of a spirited Connacht side, who ultimately left the game without anything to show for their efforts.
"It’s great when you come away from home, hostile environments, all the rest, and you get a bonus point win," Cullen said, after his side's 34-23 victory.
It had been a spectacular occasion at the new and improved Dexcom Stadium, where 12,461 people crammed in as the new Clan Stand opened its doors for the first time.
And Cullen was particularly impressed with how his side dealt with that raucous home crowd.
"We knew it was going to be a huge occasion because it's been in the calendar here for a long time.
"We know we're coming down to a pretty hostile environment against a team that's going to be hugely motivated against a lot of lads that know the group well.
"Even Stu [Lancaster] would know the group well as well. So we knew it was going to be challenging.
"Connacht started the game a million miles an hour, we started the game well, but they were flying into everything on both sides of the ball, like we thought they would.
"Credit to them for the way they went about the game, and same at the start of the second half. It was pretty tit for tat," he added.
Having played their part in a thrilling Interpro, Connacht head coach Stuart Lancaster cut a frustrated figure after they came away without even a losing bonus-point for their efforts.
"It feels disappointing. Particularly, I thought we played really well in the first half and went in in good shape at half-time, albeit it was 13-13," he told RTÉ Sport.
Having come from 7-0 behind early on, the hosts moved 20-13 ahead on 48 minutes after a wonderful Harry West try.
But the game flipped shortly after as they got stung for two tries for RG Snyman and Charlie Tector, the latter of which left a sour taste in Lancaster’s mouth.
"The second half was a big moment but then the game changed in, probably five minutes, but it was two tries in a very short space of time and ultimately that cost us.
"That's something I've spoken about in the changing room over the last few games, really, where that consistent application of doing the fundamentals consistently under pressure for the full 80 minutes is the step we need to take as a team.
"It's never one moment. But in this particular game, having been 20-13 up, the two moments, the penalty which led to Snyman's try and the Charlie Tector try, changed the game very significantly, didn't they?
"And then when you're 20-27 down and you're playing into the rain and against a rushed defence, it becomes harder and harder.
"We got back with the penalty, but obviously Frawley's try at the end was the killer."
It’s four consecutive URC defeats for the province, and a seventh loss from nine in the league this season.
But with a gap of just five points to the play-off spots, a game in hand, and some home matches ahead of them, Lancaster still believes his side can turn the new Dexcom Stadium into a fortress.
"It was a privilege to be part of the occasion and I thought the boys in the week leading into it, everyone at Connacht Rugby put so much effort into it, so it's absolutely gut-wrenching to not come away with a win.
"Obviously you've got to give Leinster credit for nailing those big moments when they happened.
"We've given ourselves a big challenge now to get in the top eight. We've played nine games and we've got nine to go.
"Obviously, as I said to the boys, it's not the end, it's the beginning.
"The stand opening with the home games we have to come, but we have to translate that emotion and energy into accuracy and do it consistently for 80 minutes."
