Mount Vernon room for up to 120 that openly markets its ability to run three events at once.
Double Door sits at 29 Elm Avenue in Mount Vernon and describes itself as a full service event company running over 10,000 square feet across three distinct rooms. The headline number is 120 guests, which is what its own home page publishes. The number that should make a couple stop is a different one: the venue advertises the ability to host three separate events simultaneously. That is a selling point aimed at a business booking a Tuesday meeting. For a wedding it means exclusivity is not the default, and nothing published says you can buy it. Beyond capacity, there is no money in public at all. No per person rate, no room fee, no minimum, no service charge. Inquiries go to a mobile number and a Gmail address. The company says it has been running events since 2000 and claims over 25 years of combined industry experience among its team.
Two things drive this page. Capacity is contested, 120 first party against 140 on a marketplace listing, and exclusivity is openly not on offer. Price is a blank. So the first email should ask for a written quote broken into room, food, beverage, staffing and administrative fee. Add two yes or no questions: can we buy the whole building for the day, and may we bring an outside caterer. Without those answers, there is nothing here to compare against another venue.
Doubledoorevents.com home page and its secondary home page, plus the Eventective listing for Double Door Event Space, read on 11 September 2026. Checked September 2026. First party means the business’s own site or rate card. Marketplace means The Knot, WeddingWire, Zola, Wedding Spot or similar. Nothing here is averaged or estimated.
The venue markets its ability to run three separate events at the same time, so your wedding may not have the building to itself unless the contract says so.
The home page states the venue has the unique ability to host three separate events at the same time. Read that as a couple rather than as a corporate client and it becomes a question you have to ask on the first call. Is the building ours, and if not, what separates our room from the party next door.
The three spaces are two full event rooms plus The Lounge at Double Door, described as a relaxed, smaller setting. No capacity is published for any individual room. Eventective records two event spaces rather than three. Nobody publishes square footage per room, so the 10,000 square foot figure is a building total, not a ballroom size.
The venue’s own home page says the space holds up to 120 guests. Eventective lists 140. Both are recorded here and neither is averaged. The distance between those two numbers is small in the abstract and large if you have a guest list of 130 and a deposit on the table.
Use the first party figure of 120 as your planning number, because it is the one the venue will be held to, and get it confirmed against your actual layout. A room that takes 120 for a seated dinner rarely takes 120 once a dance floor, a band riser and a sweetheart table are in it.
We could not find a per person rate, a room rental fee, a food and beverage minimum or a service charge on the venue’s own site or on its Eventective listing. The site routes everything to (845) 430-6273 and an email address. That is normal for a space this size, but it means you cannot compare Double Door to anything until you have a quote in hand.
When you get that quote, ask for it broken into room, food, beverage, staffing and administrative fee. A single all in number tells you nothing about what you can cut.
Double Door’s own pages describe full catering and a full service team. They do not say whether you may bring your own caterer. Eventective’s amenity list says on site catering is available and outside catering is allowed. That is a marketplace claim about a contract term, which is exactly the kind of detail that changes between a listing and a signature page. If bringing your own caterer matters to you, make it a written condition.
No end time or curfew is published. No rain plan applies, because no outdoor space is described. No building history is published, so the address has no story attached to it beyond the company’s founding year. The dataset we started from pointed at an older domain. The live site resolves at doubledoorevents.com and is the same business at the same address and phone number.
The company describes itself as a full service event outfit running since 2000, with a team carrying over 25 years of combined experience in events. That is the whole of the published background. There is no named owner, no named chef and no named event manager on the site, so you will not know who runs your wedding until you meet them.
The reason to look seriously at a space like this is cost control, and the reason to be careful is that none of the cost is published. A room of this size with in house catering sits in a very different bracket from a country club. It can be the right answer for a wedding of 90 to 120 people who want a Saturday date without a club’s minimum attached.
So make the comparison properly. Get a quote with the room, the food, the beverage, the staffing and the administrative fee shown as separate lines, then do the same at two other venues. Ask specifically what happens if your final count comes in under the number on the contract. Ask what the deposit schedule looks like and what is refundable. Ask whether The Lounge can be added for a cocktail hour and what that costs. Those answers decide whether this address works for you. The square footage does not.
