How do you explain the way to the venue to your guests?

Directions are the part of wedding planning that gets written last and read most. They usually sit in one paragraph on the invitation, written at a point when nobody yet knew where the bus stops or whether guests are allowed up the farm track.

What follows is which details guests genuinely need, how to check an address before you send it out, what changes when the day happens in two places, and where this information should live so that it stays changeable. How to organise parking and stagger arrival times is deliberately not the subject here — that is a planning question, not a communication one.

Before you send an address out, type it into two different mapping services and see where the pin lands. For buildings in town centres it is almost always right. For farms, barns, mountain huts and anything on the edge of a village it regularly lands on the wrong side of the road, at the main house instead of the event building, or on a track that guests are not allowed to use.

Four details solve the problem for good:

• The postal address for the invitation and for post.
• The access address, where it differs — the one you should actually type in.
• Geographic coordinates for every case where no mapping service knows the place. They work in any satnav.
• One sentence about the last turning, for example: past the village sign, second road on the right, the gate with the red postbox.

The last point looks old-fashioned and is the most effective. Mapping services get people close; the last two hundred metres decide whether somebody arrives on time or turns round twice. Ask the venue for it — they know the spot where guests reliably turn the wrong way and will give it to you in one sentence.

Anything beyond this does not get read. Anything missing gets asked about.

The difference between arrival time and start time is the most important sentence on the whole page. Write “ceremony at 2 pm” and you get guests pulling into the car park at 1:58. Write “arrivals from 1:15 pm, ceremony at 2 pm” and you get a calm reception. How those times fit the day as a whole is in the piece on the running order.

The line about getting home is almost always forgotten, and it is the one guests ask about in the evening. In rural areas nearly everywhere the last bus goes well before midnight, and taxis have to be booked ahead because none are waiting outside. One sentence in the invitation saves you organising lifts at one in the morning.

As soon as the ceremony and the party happen in different places, the directions do not double — they treble, because a third journey appears: the one between the two.

For that case, write three blocks instead of one. First block: getting to the ceremony, with a note on parking. Second block: the journey from there to the party, with the driving time and the time to set off. Third block: the party venue itself, with parking and getting home. The split sounds like a lot of text and is in fact shorter than one paragraph with everything mixed into it.

Be generous with the driving time between the two. A group regularly needs twice what the map says: after the ceremony there is congratulating, photographing and waiting for stragglers, and the last car often leaves twenty minutes after the first. So on a map time of fifteen minutes, plan on about forty, from the last well-wisher to the last arrival.

And say who can take whom. At weddings a good number of guests arrive without a car, and the question “how do I get to the second address?” otherwise lands with the best man. One line in the reply form — do you need a lift? — settles it in advance. How to collect extras like that alongside the acceptances is in the piece on the online RSVP.

A bus solves several problems at once — a shortage of parking, drinking and driving, guests without a car — and creates a new one: a fixed departure time everybody has to keep to.

The arithmetic is manageable. A coach seats around fifty people depending on the model. With 90 guests of whom two thirds use the shuttle, that is 60 people — so either two coaches at once, or one coach running twice and stretching the arrival by at least half an hour. What a transfer costs depends heavily on region, day of the week and time of day, so get two quotes locally before you do any sums.

If you decide on a shuttle, three details have to be in the communication, and all three have to be right:

1. Departure point and time, for the outward and return runs, with a note that the bus does not wait.
2. Who is on it, because the coach is priced per head and you need the number in advance.
3. What the alternative is, for anyone who wants to leave earlier or stay longer.

The last point decides the mood of the evening. A shuttle that runs back once at 11 pm ends the party at 11 pm, regardless of how long the venue is open. Two return runs, say at 11 pm and 1 am, cost more and rescue the second half of the night.

Paper is good for inviting and bad for updating. That is precisely the problem here: directions are the information that changes most often — the parking moves, the shuttle gains a second run, the access road closes for roadworks.

What works is a split. The invitation carries the date, the time, the place and a pointer to where the details are. The details themselves live somewhere you can change until the day before. On a wedding website that is exactly what the travel section is for: address, map, parking, train connections, shuttle times — visible to every guest, changeable by you, with nobody having to reprint anything. What else usefully lands in one place there is shown in the overview of what a wedding site can do.

Two groups still need separate attention. Guests without internet access get the details printed — half a sheet in the invitation is enough. And everyone travelling in and staying over needs the information earlier than the rest, at save-the-date time, because that is when they book.

On the wedding morning, one last rule applies: you are not the phone number for the lost. Name somebody who is reachable and knows the way, and put their number wherever the directions are.
