Co-op City Hotel Seongsan vs The Best Jeju Seongsan: for 3–4 guests, count the third-person cost before the nightly rate

Both work as Seongsan bases. The difference appears when a third guest changes not only the bed layout, but also breakfast coverage at Co-op and per-person summer pool costs at The Best.

Compare rooms the group can book

Co-op City lists a 22 m² Deluxe Double with one double, a 24 m² Deluxe Twin with a double and single, and a 28 m² Executive Double with one double. The Best Jeju lists a 27 m² Deluxe Twin with a double and single, a 27 m² Family Twin with two doubles, and a roughly 38 m² Family Suite with a king and bunk beds. Its room pages list maximum occupancy of three for the Deluxe Twin and four for the Family Twin and Suite. Check the selected room’s rules and any extra-person charge before comparing totals.

Count the breakfasts included

Co-op City’s MOBYDICK serves breakfast daily from 07:00 to 10:00; the hotel lists buffet breakfast for two guests per room. Check The Best Jeju’s terms against the room and rate selected. Compare how many breakfasts are included and the charge for other guests.

Check pool dates before treating it as an option

The Best Jeju’s official 2026 notice listed the outdoor pool from June 26 through August 31, 2026, 13:00–21:00, with cleaning from 16:00–16:30. Listed prices were ₩15,000 for adults and ₩10,000 for ages 36 months to 13; under 36 months were free, and access was for in-house guests. That season has ended. Check for a new seasonal notice before relying on pool access. Co-op City’s room pages mention a rooftop lounge called Sky Lagoon but do not establish pool access.
