Long Weekend Haus DDP: Family Rooms for Four in Seoul

When two adults and two kids share one room, the key question is whether the room code's listed "base occupancy" and "maximum occupancy" actually reach 4 people, instead of relying on a squeezed in extra bed. The six hotels below all publicly list room types that can sleep 4, covering Dongdaemun, Myeongdong, Jamsil, Itaewon and Gangnam, each with an official or booking page link so you can check live rates directly (room types and occupancy are as shown on the September 2026 query pages).

Long Weekend Haus DDP

Long Weekend Haus (롱위켄드하우스, longweekendhaus.com) DDP building is located at 15-3 Ssanglim-dong, Jung-gu, Seoul, in the same block right after you exit Dongdaemun Design Plaza (DDP). Room 502, the "Deluxe Terrace Suite," has two bedrooms and one bathroom, 38 sqm, base 2 and max 4 people; the from price shown at time of query on the booking page is current as of the 2026-09-14 query, and the fee for exceeding base occupancy is KRW 10,000 per person per night.

The two bedroom layout is key for two adults and two kids: the two rooms let everyone sleep separately instead of the whole family crowding onto one big bed plus an extra bed. If you are arriving at Incheon on a late night flight, the whole Long Weekend Haus property uses self check in kiosks, so there is no need to wait for a staffed front desk, and late arrivals are not affected. For families of up to 6, rooms 202/302/402, the "Marou Suite," base 3 and max 6, 44 sqm, two bedrooms and one bathroom, is a better fit; for multigenerational groups of 6 to 8, the room 702 rooftop unit, base 4 and max 8, three bedrooms and two bathrooms, is the only room type in the whole property that sleeps up to 8. All rooms are non smoking, pets are not allowed, guests must be 19 or older to book, and free cancellation applies to the flexible rate plan when requested within 14 days before check in. Trip.com's aggregated rating is 9.5 out of 10 based on 66 reviews (checked 2026-09-14).

Lotte Hotel World Seoul

Lotte Hotel World Seoul is a 1 minute walk from Exit 3 of Jamsil Station on subway Line 2, and the hotel connects directly to Lotte World theme park, Lotte Duty Free and Lotte Mart. The 2026 query page shows the hotel has 461 guestrooms in total. The family room type "Family Triple" (a compact suite, one bedroom, one bathroom, non smoking) has one double bed plus one single bunk bed, and the official site lists it as sleeping up to 4. There is also a Kakao Friends character themed Family Twin Room that sleeps up to 3. Rates must be checked live on the booking page at the time of query.

If two adults and two kids have a day trip to Lotte World on the itinerary, this hotel's advantage is not having to travel again, and you can leave your luggage at the front desk before checkout and keep playing until the last moment. The downside is that the rooms are somewhat dated with a standard chain hotel layout instead of a freshly renovated apartment feel.

For two adults and two kids traveling with a lot of luggage who want to cook something simple themselves, the apartment style rooms offer extra kitchen and living room buffer space compared to standard hotel rooms; the downside is that the apartment wing and hotel wing have separate entrances, so first time guests should confirm the front desk location in advance. Rates must be checked live on the booking page at the time of query.

Grand Hyatt Seoul

Grand Hyatt Seoul is located in Hannam-dong, Yongsan-gu, about a 10 minute uphill walk from Itaewon subway station. The official page shows 615 guestrooms in total, including 53 suites. The Grand Suite is 325 sqm, with a separate bedroom and living room, and offers views over the Han River and Namsan. Some room types have a built in folding sofa, and hotel staff can set it up as a bed for a 4th guest, but this incurs an additional charge, and the exact fee must be confirmed with the hotel.

For two adults and two kids who do not mind the uphill walk from Itaewon Station, this property's advantage is proximity to Namsan Park, plus indoor and outdoor pools and tennis courts at the hotel to burn off energy. Rates must be checked live on the booking page at the time of query.
