What time do wedding vendors arrive to set up?

Counted back from when the room has to be finished, which is about half an hour before the first guest. Florists and rentals typically need three hours, sound about two, and catering about three before cocktail hour opens — but the venue's own access time overrides all of them.

Who is responsible for the wedding load-in schedule?

Whoever owns the timeline — usually the planner, or the couple where there is no planner. The venue holds the constraint (access and end times) but rarely builds the schedule, and each vendor plans only their own part of it.

The load-in conflicts that show up on nearly every wedding

Load-in is where a wedding day goes wrong before anybody has arrived, and it goes wrong the same five ways almost every time.

Updated August 23, 2026

Every vendor's load-in time is calculated backwards from the same moment — when the room has to be finished — using a duration only they know. Nobody's calculation is wrong. They collide because they were each done alone.

These five are the collisions worth designing around, because they recur across venues, cities and seasons rather than being anybody's local quirk.

One · Two trades, one door, the same forty minutes

What happens: The florist arrives with eight-foot arrangements at the same time as the caterer arrives with hot boxes, and the venue has one service entrance with a lift booking attached. Both were told the entrance was available; neither was told about the other.
What it costs: Thirty to sixty minutes, taken from whichever trade is more polite, and it is almost always the one whose work takes longest to finish.
The fix: Ask the venue for the access schedule as a list of times and trades, then read it back to both. On a historic property or a hotel, ask specifically whether the lift is shared with guests.

Two · The sound check that cannot happen

What happens: A sound check needs the ceremony chairs set and the room empty of guests. Those two conditions overlap for about half an hour, and the chairs are usually set late because rentals delivered them behind the flowers.
What it costs: Either a sound check performed in front of arriving guests, or none at all — which is discovered during the processional.
The fix: Put the chair set and the sound check on the timeline as two items with a named order, not as a window. If the ceremony and the reception share a room, this is the tightest thirty minutes of the day.

Three · Deliveries that arrive without a person

What happens: Cake, rentals, signage and sometimes flowers arrive with a driver who has four more stops. They put it down somewhere and leave.
What it costs: A cake in the sun, a box of place cards nobody can find, and — the expensive version — a delivery refused because there was nobody to receive it.
The fix: Every unattended delivery needs a named receiver and a named place, on the timeline, two days before. It is the single cheapest line on this list to get right.

Four · The two-venue break-down nobody scheduled

What happens: With a ceremony in one place and a reception in another, several trades work both. The florist who dressed the aisle has to move those arrangements to the reception during cocktail hour — which is also when the caterer needs the same vehicle access.
What it costs: Either the ceremony flowers do not make it to the reception, or somebody is driving while they should be finishing the room.
The fix: Ask every vendor whether they are covering one venue or both, in writing, and put the move on the timeline as its own item with a crew attached.

Five · The venue's real access time

What happens: The rental window says noon to midnight. Vendor access is 2 PM because there is a morning event, and nobody said so until the week of.
What it costs: Every load-in on the timeline moves by two hours, which usually means the sound check disappears and the flowers are finished as guests arrive.
The fix: Get vendor access and music-off times in writing when the venue is booked, not from the contract's rental window. They are different numbers and venues quote them from memory.

The pattern underneath all five

None of these is a mistake by a vendor. Each one is two correct plans that were made separately and are incompatible — which is precisely the class of problem a shared timeline solves and a group text does not, because a group text has no state. You cannot look at a thread and see what the current plan is.

The practical version: write load-in on the timeline as items with times, for every trade, including the ones who will not be there when the guests are. Then send it to all of them and ask each to confirm their own line back.
