The key framework is a DOOR VALUE LEDGER. For two guests, sea view and Tapdong location can be compared directly. For three or four guests, the more important question is whether the room gives you a genuine second sleeping zone. The Chinese source identifies the current Family Two Room as about 46㎡ with one bedroom, one ondol room and one bathroom.
What actually changes the stay?
- One open room: enough beds may still mean one shared light, noise and bedtime zone.
- Family Two Room: a separate bedroom plus ondol room creates two sleeping zones.
- Sea View: a second pricing layer after the room layout is fixed.
- Extra person or bedding: a cost layer that must be checked in the actual rate.
Large is not the same as separated
Square metres can look generous while everyone still shares the same sleep schedule. For a family with children, or adults with different bedtimes, a real second room can matter more than adding a few metres to a single open layout.
Three or four guests should not use the two-person headline rate
Enter all adults and children first, then use the legal Family or Family Two Room product returned for that party. A cheap Standard room is not a valid family baseline simply because it appears first in search results.
Only price the sea view after the layout is solved
The source notes that the Family Two Room itself can be sold with different views. That means Ocean versus Mountain View is a valid second-stage comparison—but only after you have fixed the same room family, occupancy and bedding.
Tapdong works when the evening is part of the trip
Ocean Suites is easier to justify when you want the Tapdong waterfront, Dongmun Market and old-city evening access. If your main activity is elsewhere, do not let the sea view create another daily return route.

Final decision
Ocean Suites is strongest for groups when the second sleeping zone solves a real co-sleeping problem and Tapdong is already the right base. Do not pay for Ocean View first if the room layout itself does not work for the group.
