First cancel out the benefits both hotels already share. The source comparison treats the Jeju Shinhwa World location and the current official Basic Choice Big3 benefit as common items. Neither should be used twice to justify Marriott’s higher price.
Incremental Benefit Ledger
- Location: essentially the same resort complex — cancel it out.
- Theme Park Big3: present in the current official Basic Choice products for both — cancel it out.
- Entry room size: Landing Superior starts around 27㎡ while Marriott Deluxe rooms are around 38㎡. The extra space matters only if you will actually use the room.
- Pool: Landing’s source page explicitly notes no dedicated pool; Marriott guests have Mosil Pool access.
- Minibar: the source Marriott Basic Choice includes a minibar once per stay; treat it as an incremental benefit, not a nightly value.
- Breakfast and Water Park: rate-dependent. Count them only when the exact rate says they are included.
Who should start with Landing?
Two travelers or a small family that spends most of the day outside, mainly wants the Shinhwa World location, dining access and Big3, and does not require a hotel pool. In that case Marriott’s pool and space premium can remain unused.
Who should start with Marriott?
Travelers who will use Mosil Pool repeatedly, value the larger entry-level room, or can verify additional rate benefits such as minibar or breakfast. The premium is easier to justify when it becomes a repeated daily benefit rather than a brand label.
Do not multiply once-per-stay benefits by the number of nights
The source page specifically separates once-per-stay Big3 and minibar benefits from nightly value. On a three-night stay, the room and any repeatedly used facilities scale with nights; one-time benefits do not.

Final answer
Choose Landing first when the shared location and Big3 already solve your needs and the pool is not a hard requirement. Choose Marriott first when its larger room, Mosil Pool and verified rate benefits will be used. If Water Park is the main reason for the stay, compare a rate that explicitly includes it rather than two room-only prices.
