A beach club appears in the name, and it is worth being precise about what that means. The Atrium is the catering business. Sunny Atlantic Beach Club is the property it sits on, and the beach club sells summer cabana memberships on a different website entirely. You do not need one to get married here. The Atrium runs its own public wedding site with an enquiry form, a phone number and a banner saying it is taking bookings for 2026 and 2027. It publishes no prices, so the $10,000 below is The Knot's.
The venue publishes no number of any kind, so both figures here are The Knot's: $10,000 to start and $30,000 as typical spend. Both are event totals rather than per person rates, and The Knot itself says itemised costs are not published. Expect the first real number in a proposal.
We read the Atrium's homepage, beach wedding venues page and events page, the beach club's own membership application page, and The Knot and WeddingWire listings, on 10 September 2026. Checked September 2026. First party means the venue’s own site or rate card; marketplace means The Knot, WeddingWire, Zola, Wedding Spot or similar. Nothing here is averaged or estimated.
The membership answer rests on the absence of any membership language on the wedding site rather than on a statement by the venue, so confirm it by phone.
Two operations share one address at 2035 Ocean Boulevard. Sunny Atlantic Beach Club sells seasonal cabana memberships through its own site and application form. The Atrium at Sunny Atlantic is the events business, with its own domain, its own enquiry route and its own list of what it hosts: weddings, showers, communions, milestone birthdays, kosher events, bar and bat mitzvahs, corporate outings.
Nothing on the events side mentions membership, sponsorship or member guests. That is the basis for calling this open to the public, and it is worth understanding exactly what kind of evidence that is. Nobody at the venue told us in writing that non members may book. The wedding site simply behaves like every other catering hall on the South Shore.
On a page where the membership question can cost a couple a season, we would rather show you our reasoning than hand you a verdict.
The atrium is glass enclosed with a retractable roof directly on the ocean, and the venue describes itself as the only venue with a retractable roof on the beach. The Knot describes the same thing as a glass enclosed atrium with a retractable glass enclosure.
Take that seriously as a planning tool rather than as a photograph. On the South Shore in June, the thing that ruins an outdoor plan is a squall that arrives during the ceremony and is gone by the entree. A room that opens to the sky and then closes means nobody moves chairs, nobody relocates a band, and nobody has to make the call at two in the afternoon for a six o'clock ceremony.
The venue publishes no written weather policy at all, which is a strange gap given that the roof is its headline. Ask who decides to close it and how late that decision can be made.
The Knot lists a $10,000 starting price and says couples typically spend $30,000. It also states that packages are fully customisable with in house catering included, and that per person and itemised costs are not published. Those are whole event totals rather than rates, and none of it came from the venue.
The venue's own site publishes no per person figure, no package price, no minimum and no fee schedule. Couples are directed to call or fill in the form. We read the homepage, the beach wedding venues page and the events page.
What that means practically is that you cannot compare the Atrium to a Nassau catering hall on paper. The comparison only happens after a proposal, and the proposal is the first document in this relationship that contains a number. Get the service charge, the tax handling and the maitre d' and attendant fees written into it, because none of those are published either.
The events page lists kosher events among what the Atrium hosts. That is a first party statement, which matters, because kosher capability is one of the claims that gets copied onto marketplace listings and then quietly turns out to mean a caterer is allowed in rather than a kitchen is supervised.
The Knot separately says catering is in house and included. Neither source says which kashrut supervision applies, whether a kosher wedding uses the house kitchen or an approved outside caterer, or whether a mashgiach is arranged by the venue.
If kosher service is why this venue is on your list, that is the first phone call and it needs a specific answer rather than a yes. For everyone else, the useful takeaway is that this is a kitchen willing to run to a specification, which is worth testing with whatever your own constraint happens to be.
Here is the full evidence for the membership call. The wedding site contains no membership language. The parent beach club sells cabana memberships elsewhere, under a separate brand on a separate domain. The Atrium markets openly to the public and advertises open dates for 2026 and 2027. No page we read says a couple must be a member or must be sponsored by one.
That is a conclusion drawn from what is missing, not from a sentence anyone wrote. It is a reasonable conclusion and we would still make one phone call before falling in love with a date.
The rest of the record is blank in the usual places. No capacity on the venue's own site, no curfew, no gratuity, no rain policy, no statement about one wedding at a time. The Knot puts the venue in a 151 to 200 guest band, which is the only capacity figure published anywhere.
Parking and access are the other blanks. An oceanfront room on Ocean Boulevard in Atlantic Beach sits inside a summer traffic pattern of its own, and nothing published says where guests leave cars in July or whether valet is part of a package.
Oceanfront in Atlantic Beach with a beachfront space Zola rates to 700 seated and a package that bundles photography, video, DJ, florals and cake.
An oceanfront Long Beach hotel with rooms upstairs, a rooftop pool deck ceremony and an enclosed 4,686 sq ft rooftop venue for about 200 guests.
Ceremony in the sand at a state park beach, cocktails on the boardwalk, a ballroom for 250, and $129 per person printed on their own site.
A ceremony on the ocean sand at Jones Beach with one 250 seat ballroom behind it, and a published guest range starting at 30.
A public Montauk beachfront hotel selling a full property buyout, with an event ceiling of 250 guests and beds for only 82 of them.
An Atlantic front Westhampton Beach club with a 220 guest ballroom, a private beach ceremony area, and 2026 memberships you do not need to buy.
