It is an added stress which both sides could have done without- but a wedding which is set to clash with a vintage car rally in Princes Risborough also presents a 'unique' opportunity.
Quentin Cooper and Suba Subramaniam are getting married St Dunstan's Church on Saturday, the same weekend as the much anticipated Kop Hill Climb is held in the town.
The couple, who live in Whiteleaf, planned for their 150 guests to make the short walk from their house to the church along Peters Lane but then discovered that the country road is also going to have dozens of iconic sports cars travelling along it as part of the climb's route.
Mr Cooper, 48, joked: "Out of all the years to revive a classic car rally they decided to do it right in the middle of our wedding and right when we are getting people to and from the church!
"It is quite stressful planning a wedding and also our extension (where the reception will be held) is not quite ready yet either, adding to the fun. And then we spotted there was going to be the Kop Hill Climb!"
With the throng of wedding goers presenting a potential safety risk along the lane, the couple contacted rally organiser Tony Davies.
He has put measures in place for drivers to be warned before they set off, and also for signs to be placed on the course.
And as a gesture of goodwill Mr Davies has arranged for Miss Subramaniam, 36, to be taken to the church in style.
She will arrive in a cream-coloured 1937 MG VA Tourer, driven by his friend Mike Greasby, from Wendover, and who is taking part in the climb.
The climb is a revival of an historic rally held in the town in the early part of the 20th century. Nearly 250 vintage cars and motorcycles will travel up Kop HIll in front of thousands of spectators on Saturday and Sunday- although unlike the glory days, vehicles will make a 'commemorative' run, rather be timed in a race.
Spectator carparking opens at 9am, with the runs on the hill beginning at 10am. Admission costs 5.
