Family of Eight in Seoul: Oakwood Coex vs Long Weekend Haus

Oakwood Premier Coex Center Seoul cannot seat a family of eight, including grandparents, inside one room: its own FAQ sets standard occupancy for the four-bedroom Premier apartment at six adults, and no larger single unit is published apart from an undisclosed penthouse on the 27th floor. Long Weekend Haus DDP's 702 penthouse in Dongdaemun sleeps up to eight across three bedrooms and two bathrooms, from ₩588,000 a night on the non-refundable plan (site-published, checked 2026-09-19). For an eight-person Seoul group, splitting Oakwood into two connecting apartments or booking the Long Weekend Haus penthouse are the two workable single-property paths; the sections below cover both plus four more options with their own capacity and price.

Long Weekend Haus DDP

Long Weekend Haus DDP sits in Jung-gu at 15-3 Ssangnim-dong, a short walk from Dongdaemun Design Plaza, and its 702 penthouse, the only unit in the 12-room property rated for eight guests, has a base occupancy of four and a maximum of eight across three bedrooms and two bathrooms at 69 square meters, priced from ₩588,000 a night on the non-refundable plan or ₩654,000 a night on the free-cancellation plan (official site, checked 2026-09-19).

Every unit, including the penthouse, has a self check-in kiosk, so grandparents arriving on a late flight do not need to time their arrival to a front desk shift. Check-in starts at 15:00 and check-out is 11:00, Wi-Fi is free throughout, and the whole property is non-smoking with no pets allowed. Stays of three nights or longer receive a 10% discount on the published rate, and cancellation is free up to 14 days before check-in on the flexible plan (official site, observed 2026-09-14). If your group runs to eight people across three generations, the two bathrooms in the penthouse mean grandparents are not sharing one bathroom queue with four grandchildren. Book through stay.longweekendhaus.com or through the same listing on Trip.com (checked 2026-09-14). The penthouse has three bedrooms instead of four separate rooms, so a family that wants every adult in a fully separate room would need to add a second unit; extra guests beyond a room's base occupancy add ₩10,000 per person per night.

Oakwood Premier Coex Center Seoul

Oakwood Premier Coex Center Seoul sits on Teheran-ro in Gangnam-gu, a 10-minute walk from Samseong Station on Line 2 and adjoining COEX Mall, and its largest standard apartment, the 4-Bedroom Premier at 193 square meters, has an official standard occupancy of six adults, with studio and superior rooms priced from around $188 a night for two adults on a recently checked date.

The property's own FAQ sets extra-person charges at ₩40,000 per additional guest across studio, one-, two-, three- and four-bedroom types, and every apartment has a full kitchen with refrigerator, microwave, dishwasher and washing machine, useful for a multigenerational group cooking its own meals between excursions. Check-in begins at 15:00, and guests are asked to notify the property of arrival time at least 72 hours ahead. A fifth-floor playroom and crib rental suit young grandchildren, and rollaway beds cost ₩72,600 a night where a room's category allows one. For eight guests including grandparents, the 4-Bedroom Premier's six-person cap means booking two connecting apartments, for example a 4-Bedroom Premier for six plus a studio for two, or asking the property directly about the 27th-floor penthouse, whose maximum occupancy is not listed on the official room pages. Children 12 and under must stay with an adult, and breakfast runs ₩48,000 for adults and ₩24,000 for children if the group chooses the buffet instead of the in-room kitchen. If your grandparents want a quiet retreat away from the children's rooms, ask specifically about the penthouse floor when you call; the standard four-bedroom option is confirmed for six, not eight.

Lotte Hotel Seoul Executive Family Suite

Lotte Hotel Seoul's Executive Family Suite belongs to a Lotte Hotels and Resorts lineup whose Myeongdong sibling property, L7 Myeongdong by Lotte, sits about 100 meters from Exit 9 of Myeongdong Station on Line 4, with documented room types topping out at a Standard Family Twin Room that sleeps three across one bedroom, one single bed and one double bed, from USD 145 a night on a recently checked rate.

None of the published Lotte-brand room data reviewed for this comparison lists a configuration that sleeps eight in one room; the largest documented unit is the three-person Family Twin. Superior Double and Twin rooms run from USD 199 to USD 270 a night depending on view, and the property books through the hotel's own site and through Booking.com, Expedia, Trip.com, Agoda, Klook, momondo and HotelsCombined. For grandparents traveling with young children, a Lotte-brand family suite gives daily housekeeping and an on-site restaurant without a kitchen, so an eight-person group needs two or three separate rooms instead of one apartment with cooking facilities.

Signiel Seoul Signiel Suite

Signiel Seoul's Signiel Suite occupies the hotel inside Lotte World Tower in Songpa-gu, near Jamsil Station, and is arranged as a single-suite hotel category, not a multi-bedroom apartment, so seating eight across three generations means booking multiple suites side by side.

The suite books through the hotel's own reservation channel and through luxury travel platforms including Kiwi Collection, Remote Lands and LHW; Signiel Seoul's suite occupancy and nightly rate are set at booking based on floor and view, per the property's own reservation channel (checked 2026-09-14). If you want a river-facing room for the grandparents specifically, request it when you call instead of leaving room assignment to check-in. Two or three suites booked together give each generation its own bathroom and living space, at the cost of splitting the group across separate keys instead of one shared apartment.

Grand InterContinental Seoul Parnas Family Connecting Rooms

Grand InterContinental Seoul Parnas connects directly to Parnas Mall and COEX Mall and sits a short walk from Samseong Station on Line 2, and its Family Connecting Rooms pair two Classic rooms, each about 430 square feet with two single beds and a daybed, at $311 total for one night (Dec 18 to Dec 19 listing).

Connecting rooms are offered on request and depend on availability for the date requested, so a family should confirm the connecting pair when booking instead of assuming it will be assigned automatically. No kitchen is listed in any room type, and club-level access covers two guests before a surcharge applies for additional guests. For eight including grandparents, two Family Connecting Room pairs, four rooms in total, would be needed, since neither the Classic room nor the connecting pair is documented to sleep more than four at once. A cancellation made after 18:00 the day before check-in on some packages is charged for one night, so confirm the specific package terms before the trip.

Outside these five properties, Airbnb's Gangnam market lists many independently hosted apartments built for exactly this group size; one Airbnb Gangnam Large Group Apartment Listing offers two queen beds and four single beds across two units near Seoul Subway Lines 2 and 7, enough sleeping space for eight without splitting the group across two different buildings. Airbnb listings are individually hosted, so cancellation terms, check-in hours and kitchen equipment vary by host and should be checked on the specific listing page before booking.
