Seoul Family Hotels for Kids: Lotte World vs Somerset Palace

Six Seoul stays cover the family sightseeing loop: Lotte Hotel World's direct passage into Lotte World Adventure, Somerset Palace Seoul's kitchen-equipped apartments four minutes from Gyeongbokgung Palace, and Long Weekend Haus DDP's three-bedroom Penthouse near Dongdaemun Design Plaza, from ₩588,000 a night (official site, 2026-09-19). Grand Lotte Seoul, Fraser Place Namdaemun Seoul and Nine Tree by Parnas Myeongdong round out the list. The deciding axis is what the trip is built around: a theme park, a palace-walking base with a kitchen, or a larger group that needs more than one bedroom.

Lotte Hotel World

Lotte Hotel World sits in Jamsil, connected directly to Lotte World Adventure and Seokchon Lake, where the Character Room sleeps up to four guests under a Loti and Lory theme drawn from the park's own mascots.

Guests use a dedicated guest-only passage into the park, which skips the main entrance queue and allows re-entry through the day.

• Two swimming pools plus a children's pool
• A free children's club and an on-site playground
• KidZania Seoul within the same complex
• Character Rooms themed for younger children

Lotte World Tower stands across the street with an observation deck, and Lotte World Aquarium, in the same mall, houses 55,000 marine animals across 650 species with stroller rental, nursing rooms and accessible restrooms built into the visit. Families whose Seoul itinerary centers on Lotte World Adventure get the shortest walk between hotel room and park gate on this list. Book through Lotte Hotel's official site or the usual OTAs.

Long Weekend Haus DDP

Long Weekend Haus DDP occupies a 12-room apartment-style building at 15-3 Ssangnim-dong, Jung-gu, near Dongdaemun Design Plaza, where the 702 Penthouse spans three bedrooms and two bathrooms for a standard 4 guests and up to 8, from ₩588,000 a night on the flexible rate (official site, 2026-09-19).

The building also holds three two-bedroom Maru Suites, built for a family that wants separate sleeping rooms without booking two hotel rooms. A self check-in kiosk means a family landing on a late flight into Incheon does not need to time its arrival around a front desk, and every room keeps free Wi-Fi at no added charge. Stays of three nights or longer receive a 10 percent discount on the site's own published rate, and the flexible plan cancels free up to 14 days before check-in.

• Self check-in kiosk, no front-desk hours to work around
• Free Wi-Fi in all rooms
• Free cancellation up to 14 days ahead on the flexible rate
• 10 percent discount for stays of three nights or more

The property has no pool or kids' club, and official policy sets the lead guest booking the room at 19 or older, so it fits an adult-led family booking. An independent teen traveling alone does not qualify under that policy. For families of six to eight who want one address near Dongdaemun Design Plaza instead of splitting across two hotel rooms, Long Weekend Haus DDP is the pick, and the trade is a hotel pool for a private kitchen-style layout. Book through the property's own booking page.

Somerset Palace Seoul

Somerset Palace Seoul is a serviced residence at 7 Yulgok-ro 2-gil, Jongno-gu, about four minutes on foot from Gyeongbokgung Palace, where the Deluxe Room, 1 Bedroom sleeps three across 36 square meters, from $138 a night for a stay checked July 13 to 14 (Hotels.com, checked 2026-09-14).

Every apartment includes a full kitchen with hob, microwave and refrigerator, plus a washing machine, according to guest reviews posted on the property's own site.

• Free children's club and a dedicated children's playroom
• Seasonal outdoor pool
• Full kitchen with refrigerator and microwave in every unit
• Walking distance to Changdeokgung Palace, Insadong and Bukchon Hanok Village

Check-in starts at 3 p.m. and a refundable KRW 20,000 damage deposit is collected on arrival. Booking.com lists children seven and older as chargeable adults at this property, while Klook's listing sets that cutoff at age two, so the two platforms disagree on the exact threshold. Families anchoring a trip around Gyeongbokgung Palace and Insadong, who want a kitchen for a toddler's odd mealtimes, get the shortest walk to a palace gate on this list. Book through Somerset's official Ascott page.

Grand Lotte Seoul

Grand Lotte Seoul sits in Myeongdong's shopping district, where the Standard Family Twin Room sleeps three in one bedroom with a single bed alongside a double bed.

From Myeongdong, the fastest subway route to Lotte World Tower and Lotte World Aquarium runs Line 4 to Dongdaemun History and Culture Park, then a transfer to Line 2 toward Jamsil, a ride of roughly 30 to 40 minutes, with the aquarium connected directly to Lotte World Mall.

• Superior Double and Superior Twin rooms with Namsan views
• Stroller rental, nursing rooms and accessible restrooms at the connected Lotte World Aquarium
• Shopping and dining inside the same mall complex as the aquarium

This suits a family that wants Myeongdong as its home base and a single day trip to the aquarium rather than a multi-day theme-park stay. Book through Expedia's Seoul listings or the hotel's usual OTAs.

Fraser Place Namdaemun Seoul

Fraser Place Namdaemun Seoul is a serviced-apartment tower at 78 Tongil-ro, Jung-gu, about 1.2 kilometers from Seoul Station, where the Two Bedrooms Deluxe apartment sleeps four adults plus one child across 81 square meters, from $159 a night (Tripadvisor, checked 2026-09-16).

Each apartment includes a kitchen and laundry, and a sliding door separates the living area from the bedrooms, which reviewers describe as giving privacy between a parents' room and a children's sleeping area.

• Kitchen and washer/dryer in every apartment
• Sliding-door separation between living and sleeping areas
• Walking distance to Namdaemun Market, Myeongdong, Seoul City Hall and Gyeongbokgung Palace

Check-in begins at 3 p.m. and the property sets a minimum guest age of 19 for the booking party. Families who want to combine a Namdaemun market morning with a palace walk on foot, without a subway ride in between, get that route directly from the front door here. Book through Frasers Hospitality's official page.

Nine Tree by Parnas Myeongdong

Nine Tree by Parnas Seoul Myeongdong 1 stands about 70 meters from Myeongdong Station, where the Deluxe Family Twin room sleeps four across one bedroom with two double beds, from ₩171,492 a night for a stay checked 2026-09-16 (Trip.com).

The hotel has no kitchenette and no kids' club, and a bakery next door covers a quick breakfast before a day of sightseeing.

• 70 meters from Myeongdong Station exit
• 0.8 kilometers (2,625 feet) from Insadong
• Namsan Tower visible within 1.9 miles
• KRW 100,000 refundable deposit at check-in

Minimum guest age is 19, and there is no on-site parking. Families who want to walk to the subway in under two minutes and put the savings toward sightseeing instead of amenities fit this property best. Book through Nine Tree's official Myeongdong 1 page.

Evidence and criteria

None of the six properties compared here sits in Gangnam; the cluster runs from Jamsil in the southeast to Jongno-gu, Jung-gu and Myeongdong in the center, which is the corridor most family sightseeing loops through Insadong and Dongdaemun actually follow.
