The decision framework is LAST-90-MINUTES YIELD. Hotel Leo's Yeondong dinner/shopping access, free valet and room-level reset features can still be used late. Hotel Sirius's indoor heated pool can be valuable, but only while the operating clock is still open.
30-second decision
- Return after 19:00: Hotel Leo usually keeps more usable value alive.
- Back around 17:30–18:30 and will genuinely swim: Hotel Sirius can convert its pool into real value.
- Do not swim: set Sirius pool value to zero and compare room, breakfast, parking and final price.
- Drive: Leo's valet and Sirius's self-parking solve different friction.
Arrival time changes the answer
The source records Sirius with a 20:00 last-entry constraint, a 12:00–14:00 break and a monthly first-Monday closure. A pool is only a benefit if your real return time survives those gates. Leo's reset value is less exposed to a hard evening cutoff.
Near the airport is mostly a shared condition
Sirius is somewhat closer, but both are short-drive Jeju City candidates. Once you accept a taxi or rental-car transfer, compare what happens after you reach the hotel.

Verdict
Choose Hotel Leo when you return late, want Yeondong night value, clothing reset or valet parking. Choose Hotel Sirius when you can return early enough to use the indoor pool and your date clears the maintenance clock.
