To travel hopefully is a better thing than to arrive. Wise words from Robert Louis Stevenson.
But it was in more than hope that the DUP first boarded its campaigning Brexit bus five years ago.
It may be a reverse analogy, leaving Europe rather than heading off for a break in the sun. But, like booking a holiday, the photos in the brochure looked appealing. When you get there the reality is somewhat different.
You've been on the plane, grabbed the baggage on arrival, only to walk out of the airport to find the destination has changed en route. And you've got the wrong suitcases.
And the DUP's road to Brexit seemed to start out so well.
In his pre-Downing Street days Boris Johnson was given a hero's welcome at the party's annual conference in October 2018.
It's somewhat ironic now that his speech to delegates evoked memories of an ill-fated piece of Ulster history.
"The Titanic springs to mind, and now is the time to point out the iceberg ahead," he said in warning of the consequences of letting Brussels continue to set the rules.
He received a rousing ovation, but one that's unlikely to be repeated any time soon as we are committed to a marriage of convenience signed up for with a dowry of 'confidence-and-supply'.
But it wasn't long before confidence in then-Prime Minister Theresa May was in short supply.
With Westminster in chaos, she called a snap general election for June 8, 2017.
Britain, she said, needed certainty, stability and strong leadership following the EU referendum.
Her gamble failed, and though the Conservatives clung to power, it was with a vastly reduced majority. For the DUP it initially looked like its own gamble of piling in behind Brexit would pay off as it was thrust into the position of kingmaker. The Prime Minister needed the party's votes in the Commons.
But even that apparent position of power proved a false dawn for the DUP.
It was never going to last, and although Mrs May limped on, the damage was done.
Failed vote after failed vote in the Commons ended with the Prime Minister bowing to the inevitable and standing aside.
With her replacement by the same Brexit-championing Johnson, so lauded by the DUP a few months before, it seemed a perfect fit.
But when he swept home in the general election of December 2019 with a huge majority, the DUP found itself cast hopelessly adrift, no longer central to the UK Government's needs.
Stick a Darth Vader mask over the unruly mop of blond hair and you could almost hear him saying: "I am altering the deal. Pray I don't alter it any further."
The DUP had woken early from the dream it had been selling Northern Ireland to find out it was just that, a dream. Shoved under its own Brexit bus, there's been a soft bump and the driver has barely blinked.
Bogged down by deal or no-deal, backstops by the backdoor, and Irish Sea borders, the pipe-dream of that smooth and clean Brexit has long since gone up in smoke.
It's quite the predicament for a party that emerged after the general election of 2017 as one of the most important groups in Westminster - offering the Conservatives the promise of a safe majority in the House of Commons.
For two years the DUP position was simple: the UK in its entirety had to leave the EU on the same terms.
Put simply, Northern Ireland wasn't to be left behind.
While not exactly left behind, the local MPs will instead find themselves sitting on the sidelines as their Commons colleagues gather to vote once and for all in favour of the Brexit deal.
The DUP finds itself in a position of voting against something it believes in.
For different reasons, it will be joined in its opposition by SDLP and Alliance MPs.
"Marching people up to the top of the hill before running back down and denying you had anything to do with it is the DUP's signature move," said SDLP MP Claire Hanna.
"Voting against the Brexit deal is an attempt to deflect the consequences of what they campaigned for and enabled for years.
"The DUP own Brexit."
Vote against it its MPs will, for what it's worth, a face-saving stand on principle rather than any meaningful contribution to the future of the UK.
Undeterred, DUP chief Brexit cheerleader Sammy Wilson has continued to bang that particular drum.
"I can guarantee that once people in Northern Ireland - unionists and nationalists, Catholics and Protestants - look at the benefits of being part of the fifth biggest economy in the world, and an economy that I believe will grow as a result of Brexit and strengthen as a result of Brexit, I believe that they will understand that their future lies with Britain," he said.
But rather than being front and central to the orchestra, those drums can now barely be heard as Johnson conducts his Westminster ensemble to a different tune.
What happens next is that the treaty will be signed in Brussels today.
The paperwork will then travel to London for Johnson to sign.
Downing Street said an RAF plane will transport the international treaty, accompanied by UK and EU officials.
A day later the UK will formally sever ties with the 27-nation bloc.
And no vote against it in the Commons by anyone representing Northern Ireland, particularly the DUP, will make a blind bit of difference.
