Oxford United fans are waking up to the U's making another trip to Wembley after the team did enough to secure victory against Millwall.
A packed Kassam Stadium saw Oxford lose 1-0 on the night but win 2-1 on aggregate and fans are now heading for Wembley on April 3.
The U's opponents will be Fleetwood or Barnsley, who play tomorrow night in the northern area final.
The win immediately brought back memories of the team's win at Wembley in 2010 against York City in the Conference play-off final in 2010.
It will be the team's third trip to Wembley - older fans remember the Milk Cup final win in 1986 - and so far they have never lost.
One young fan looking forward to the March to the Arch is Josh Walker, 11, from Chinnor.
He was at the play-off game in 2010 and said he was now looking forward to a return to Wembley.
The under-12s goalkeeper for Chinnor Football Club was given departing right-back George Baldock's shirt following Saturday's FA Cup clash against Blackburn Rovers.
Tickets for Wembley are expected to go on sale after the northern area final of the competition has been played tomorrow.
Following last night's win Matthew Booker, 33, from Wantage, said: "I went to the 2010 play-off final, I'm looking forward to going back.
"I think we will have 20,000 or 30,000 going to Wembley - it will be an unforgettable day out."
U's fans Nick Sanders was celebrating this morning but tweeted that the U's needed to focus on winning promotion.
More than 10,000 supporters created an electric atmosphere as the U's reached Wembley once again.
Kevin Vickers, 56, was at the game with his son Jayden, 11.
Mr Vickers, from Headington, said: "It will be great to go back again, but especially now that I can take my son with me.
"We have not been for a long time and there have been some really bad times at our club.
"Now it is good to see we are on the way up and a trip to Wembley will be fantastic."
Season ticket holder pals Ian Grant, Dick Walsh and Malcolm Holley all travelled to Wembley in 1986 and in 2010 to cheer on the U's and saw their side reach the hallowed turf again last night.
Mr Grant, 60, said: "A third trip to Wembley will be great.
"There was more riding on the Millwall game than the Blackburn match [in the FA Cup].
"We were never going to win the FA Cup, but now we have got a great chance at winning this.
"Promotion is what we want and going to Wembley will be a big bonus."
Millwall brought 1,478 travelling supporters but United's fans kept the decibel levels high to drown out any attempts the visitors made to spur on their team.
Luke White from Wallingford brought along brother John for his first ever Oxford United game and stood side-by-side with his fellow loyal fans as they vanquished so much of the pain of recent years.
Luke, 17, said: "We will try to get tickets for Wembley.
"It will be a great day out."
Eleven-year-old John added: "It is just amazing for my first ever game."
Season ticket holder Greg Morris from Yarnton said going to Wembley will be "epic."
He added: "Trips like this are all for the fans.
"You come to every league game and see the team perhaps win or lose but everyone remembers cup runs and cup wins.
"I went in 2010 and it was brilliant.
"This time we will be able to bring more younger fans on board which I think would really help the club."
Fans had travelled from far and wide to chew their fingers to the bone on a historic night, including 56-year-old Dave Underwood, who has been supporting the club for 25 years, from Basingstoke in Hampshire.
The season ticket holder said: "The first time we went to Wembley for the League Cup final was the biggest game in our history, and then in 2010 that was the biggest game because it meant so much.
"This time it would not have broken my heart if we didn't get there, but it should be a great day out."
