A 117-guest wedding needs valet for roughly 55 to 65 cars. Book the company once you have a venue and a guest estimate, walk the site for arrival lanes and stacking space, confirm the venue accessible parking obligations, and staff for one compressed arrival peak rather than a steady trickle.

Guest count is not the number that decides your parking. Vehicles are. The Federal Highway Administration measures how many people travel per vehicle, and its 2022 National Household Travel Survey puts social and recreational occupancy at 1.99 people, with a margin of error of 0.19. That is the closest national figure to wedding travel.
The Knot Real Weddings Study, which surveyed about 10,474 US couples married during 2025, puts the average wedding at 117 guests. Applying the survey occupancy to that average gives roughly 59 vehicles, or a range of about 54 to 65 once the margin of error is carried through. That arithmetic is ours, not either source’s claim, and it is a planning starting point rather than a promise.
Two things move the real number. Guests bussed or shuttled from a single hotel collapse it. A guest list spread across a wide area, or one skewed toward couples arriving separately, pushes it up. The survey itself notes occupancy fell across every trip purpose between 2017 and 2022, and states plainly that “considering the associated MOEs, these differences are statistically significant.” Fewer people per car means more cars for the same guest list.
The 117-guest average sits below the 131 The Knot recorded for 2019, and has moved slowly since: 115 in 2023, 116 in 2024, 117 in 2025. Guest counts also split by generation, with Gen Z couples at 129 and Gen X at 90. If your wedding is materially larger or smaller than the average, plan against your own list rather than the headline.
This is the detail wedding planning checklists routinely miss. Under the ADA Standards, required accessible spaces are scoped to the parking facility, and the count scales with lot size: 1 to 25 spaces requires one, 26 to 50 requires two, and 76 to 100 requires four. The US Access Board, which writes the Standards, also requires that “at least one of every 6 accessible spaces, or fraction of 6, in each parking facility must be sized to accommodate vans.”
Running valet does not transfer or remove that obligation. Ask your venue directly who is responsible for it before the day, because discovering the answer during arrivals is expensive and public.
Weddings are the hardest arrival pattern in event parking. Guests turn up inside a narrow window before the ceremony, then leave in a similar cluster at the end. Staffing to the average arrival rate across the evening produces a queue at precisely the two moments guests are watching. Departure needs its own answer rather than an assumption that arrival staffing carries over.
