The core framework is the POOL MAINTENANCE DATE GATE. The Chinese source records the 2026 rooftop heated-pool season as 1 April–31 October, generally 10:00–21:00 and free for hotel guests, but with named monthly cleaning closure dates. A free amenity still has date risk.
When does the pool value become zero?
- Named maintenance dates: the source lists 28 Apr, 26 May, 23 Jun, 21 Jul, 18 Aug and 22 Sep 2026.
- November–March: do not give the rooftop pool value outside the announced 2026 season.
- Normal April–October dates: the pool can be a real benefit if your itinerary leaves time to use it.
- Families: kids' facilities can still help on a bad-weather or closure day, but they do not prove the pool is operating.
A one-night stay makes the calendar more important
If you stay several nights, one closure day may only reduce value. On a one-night booking, the same date can remove the pool completely from the stay. That is why the calendar should be checked before comparing platform prices.
Family pricing still starts from legal occupancy
For three to six travelers, enter the full party first and use the actual Family or Suite product returned for your dates. Do not use a two-person Superior headline rate as the group baseline.
Breakfast numbers can vary across current feeds
The source notes broadly similar breakfast hours around 07:00–10:00 but conflicting child-price figures across current OTA feeds. The safe decision is to use the exact selected rate and hotel notice instead of hard-coding one child price into the booking calculation.
Compare exact-property contracts
Fix the stay date, all guest ages, exact room, breakfast and cancellation. If the pool is a hard requirement, put the 2026 pool calendar in the final pre-payment check.
Final decision
Casaloma is easiest to justify when the rooftop pool is actually open on your date and you will use it, or when the Seogwipo location and room product already work without it. Reprice the stay when your only night falls on a maintenance closure or outside the announced season.
