The Lannin

The Carltun building, gutted and reopened under a new name in September 2023

The scope of the work is described plainly in the venue's own account: brand new kitchens, bathrooms, flooring and ballroom. Brides of Long Island carried that description and named co owner Elias Trahanas. Trahanas Hospitality Group also runs concessions at Jones Beach and Robert Moses State Park, and it operates three venues inside Eisenhower Park, according to The Long Island Times in March 2024. Two of those share this address: The Union, a restaurant, and The General.

What nobody publishes is the building itself. No construction year, no architect, no original estate name. The origin of the name Lannin is not stated anywhere we could find. If someone on a tour gives you a date for the structure, treat it as a claim and ask where it came from.

One ballroom at 450 seats, and a glass room doing the ceremony work

The first party room list is short. The Ballroom, the Patio with fountain views, the Garden, a grand staircase, and bridal suites fitted with six salon chairs. Capacity is published for the whole venue at 30 to 450 guests, and the weddings page puts 450 seats in the ballroom. There is no per room breakdown, which matters if you are walking 120 people into a room built for 450.

Brides of Long Island adds three things the venue's own pages leave out. A glass room used for ceremonies or cocktail hour, with windows that open onto the garden. Separate suites for each side of the party upstairs, and a separate kosher kitchen on site. The glass room is the one to stand in. It is the piece that makes an April ceremony survivable.

The Knot lists capacity as 300 plus. WeddingWire and Eventective both say 450, which matches the venue. Use the venue's figure.

A $1,500 ceremony fee is the only price anyone prints for The Lannin

There is no per person figure on thelannin.com. Not on the weddings page, not on the amenities page, not on the corporate or private party pages. There is none on The Knot, WeddingWire or Eventective either. The Knot displays an average cost of $26,493, which is a Knot model output for the area rather than a rate this venue quoted, and it sits beside line items marked contact for pricing.

The one hard number is a ceremony site fee of $1,500, identical peak and off peak, published on The Knot and on WeddingWire. Both are marketplace listings rather than the venue's own rate card. WeddingWire itemizes what that fee is said to cover, including the bridal suite, chairs, china, linens, glassware, lighting and sound, parking, setup and cleanup. Neither listing shows a reception site fee.

No food and beverage minimum is published. No service charge, administrative fee, maitre d' fee or bridal attendant fee appears anywhere we looked. The venue does describe two maitre d's, personal attendants and a day of coordinator as part of the service. Whether any of that lands as a line item on the contract is not stated.

Nobody publishes an end time for a venue sitting inside a county park

The Lannin says the timeline is customizable with flexible start times, and that the bridal suite is available from 10 AM at no charge. It does not say when the night ends. The Knot, WeddingWire and Eventective do not answer it either.

That gap is worth pressing because of the address. This is Eisenhower Park, a Nassau County park, and county parks carry their own hours. Whether a park rule reaches a private event held under concession is not published anywhere, and we are not going to guess at it. Get the contract end time and the overtime rate in writing before you sign.

The same silence covers weather. Indoor and outdoor ceremony spaces both exist, and WeddingWire lists covered and uncovered outdoor options. There is no written rain call, no deadline and no fee. Confirm in writing what a move indoors costs and who gets to make that decision on the morning.

Outside vendors are allowed here, and the catering is not up for discussion

WeddingWire's FAQ answers yes to outside vendors and yes to pets. Catering is in house under executive chef Tom Gloster, so the kitchen is theirs and the band, florist and photographer are yours. No approved vendor list is published and no outside vendor fee is published. Neither answer appears on thelannin.com, so both are marketplace answers.

One wedding per day is stated on the venue's own pages twice and repeated by The Knot and by Brides of Long Island. For a property that also runs a restaurant and a second venue on the same site, read that promise closely. One wedding does not necessarily mean one event. Ask what else is on the books across the three Eisenhower Park rooms on your date.

It suits a Nassau wedding that wants a kosher kitchen and a park

The reasons to look are the kosher kitchen, a golf course setting inside a public park minutes from the Meadowbrook, and a room that takes 450 without a tent. The tasting is for the couple plus two guests each, roughly two months out, which is a genuine perk when both families have opinions about the entree.

The reason to hesitate is the pricing blackout. You cannot compare this venue against anything until someone emails you a sheet. Ask for the per head rate by day and season, the administrative or service charge percentage, whether sales tax applies on top of that charge, and the ceremony fee in writing. The $1,500 you found online came from The Knot, not from them.
