Or be original!  Look for some method of transport that reflects your interests or job (JCB, tractor, company van).  If you are going by motorbike, don't wear the full white dress however - there have been some very nasty accidents!

For a London wedding, a black cab looks very chic - but remember to take a sheet to cover the seat - if the last person put their dirty shoes on it, your day could be ruined!
