Stanley turned on the style to finish the season with back-to-back wins and send the Accy fans home happy for the summer.
There was a party atmosphere at the Store First Stadium with both teams safe and the Reds treated the near-2,000 crowd to some fine football during the first half, racing into a 2-0 lead inside 19 minutes.
James Gray then scored his second of the game within two minutes of the restart before Wimbledon finally rallied.
The Dons converted a 73rd-minute penalty as Stanley eased up and although they pulled another goal back in the 89th minute, the 3-2 scoreline flattered the visitors given the dominance of Stanley’s first-half performance.
However, the Reds did get a helping hand from a woeful Wimbledon defence which was clearly already in holiday mode.
Manager James Beattie made just one change to the side that won at Oxford the previous week, with Michael Liddle coming in for injured loanee Adam Buxton.
And Stanley produced some crisp passing from the outset. A decent attack looked to be over when Josh Windass’s pass towards Kayode Odejayi was cut out, but Alan Bennett’s pass back towards Will Antwi went wide of his central-defensive partner.
That allowed Odejayi to run through on goal and the striker, playing his final game on loan from Rotherham, took one touch before sidefooting into the bottom corner from 20 yards for a sixth-minute opener and his eighth goal of the season.
The Reds kept the pressure on with Nicky Hunt playing a one-two with captain Luke Joyce before seeing his low cross cleared behind by Antwi. From the resulting corner, Windass’s outswinger found Gray eight yards out and despite reaching backwards, the Stanley striker managed to get enough on it to steer a looping header just inside the far post.
For a moment it looked as though the goal had been disallowed but Gray was spared the embarrassment of seeing his celebration cut short.
Dons boss Neal Ardley was screaming at his players from the touchline, urging them to up their game, and they did briefly as Aaron Morris’s cross was headed wide by Kwesi Appiah.
The Reds responded with Gray directing a tame header goalwards from Hunt’s diagonal ball while Gray and Will Hatfield saw cut-backs blocked following more good wing play.
The visitors threatened again as Marcus Bettinelli did well to turn wide Peter Sweeney’s long-range strike while Jack Midson sent a header well wide.
But Stanley were firmly on top, Hatfield seeing a shot shot blocked from Odejayi’s through ball.
Piero Mingoia then fed the ball inside for Gray, whose 20-yard strike hit the outside of a post, and Gray went close again just before half-time, testing keeper Ross Worner at his near post.
Either Antwi or Bennett could have made way at the break as both were given a torrid time by Gray and strike partner Odejayi, but it was Dons captain Bennett who was replaced by Darren Jones.
Yet he could not prevent them going three down moments after the restart.
Hunt’s shot was turned wide by Worner and from the corner, again taken by Windass, Gray rose highest to head home from six yards.
Ardley made his other two changes shortly after and he saw an immediate response as substitute Danny Hylton was denied by Bettinelli from a tight angle.
Bettinelli then punched a free-kick clear and with the Fulham loanee out of goal, visiting midfielder Sammy Moore hooked the ball over from the edge of the box.
Tom Aldred was caught flat-footed as Hylton raced onto his own flick to get in behind the Stanley centre-half, who tripped Hylton to concede a penalty, and Midson confidently sidefooted in the spot-kick.
Aldred came to the rescue moments later, though, to prevent Hylton pulling the trigger after being gifted possession by a rare stray pass by Joyce.
A fierce Midson drive was then parried to safety by Bettinelli before Hylton got to the byline to cross for Appiah to head goalwards at the far post.
Bettinelli scrambled across goal to push it out but the referee’s assistant on the far side flagged to indicate the ball had crossed the line.
Bettinelli was adamant it hadn’t. He was even booked for protesting.
But despite five minutes being indicated for stoppage time, Stanley made sure they saw out the victory and ended the season on a high.
“If we are nit-picking, the lads wanted to get up to zero goal difference,” said Beattie, whose side finished on minus-2.
“We started well and imposed ourselves on the game.
“Neal (Ardley) said his lads weren’t at the races for an hour and we could have been three or four up at half-time.
“Then they rallied. I said at half-time the only way they’d get back into the game is from our mistakes and by us taking our foot off the gas, which we did in the second half.
“We held on for a result but overall I’ve not got a bad word to say about these boys.”
