What the 2021 Korea Grand Sale actually did for lodging revenue
Hi, we're ONDA — the B2B platform leading digital transformation in Korea's lodging industry.
Korea Grand Sale ran multiple rounds in 2021 — regional editions, nationwide editions — and we were curious: in the middle of a pandemic, what impact did it actually have?
So we pulled the numbers. Using real sales data from ~40,000 properties transacting through ONDA's GDS (Global Distribution System), we compared 2021 vs. 2020 to see how the campaign moved the needle for lodging revenue.
We also split the data: properties that joined vs. those that didn't. Spoiler: there's a clear difference. Stick with us.
(Note: All 2021 ONDA lodging metrics are indexed to 2020 sales = 100.)
1. Korea Grand Sale GMV: 2020 vs. 2021
We looked at overlapping campaign windows: Nov 10–23, 2020 vs. Nov 9–22, 2021.
Result: total lodging GMV rose 13.9% year-over-year. Travel anxiety? Roughly the same. Demand held steady.
But here's the kicker: the 2021 nationwide edition ran longer — coupon redemption + check-in dates extended to Dec 23. Compared that to 2020, and the takeaway is clear: longer campaigns = bigger impact.
Resorts saw GMV more than double YoY.
How did different property types perform?
Resorts led the pack — GMV jumped 122.7% YoY.
Pool villas also climbed 31% YoY. Both categories skew pricier, which signals something interesting: with international travel still off the table, demand shifted upmarket toward "premium domestic stays."
And motels? Up 28.6% YoY — above the category average. Makes sense: when you're offering ₩20,000–30,000 coupons, the discount hits harder on lower-priced inventory. Motels captured that value.
2. Joined vs. Didn't Join: What Changed?
First: 72.3% of properties in ONDA's network joined the 2021 nationwide edition. 27.7% didn't.
So what did participation actually buy you?
We compared two windows: the campaign period (Nov 9–Dec 22, 2021) vs. the pre-campaign period (Sep 18–Oct 31, 2021). Same properties, different timing.
1) More properties got bookings
For properties that joined, the share with at least one booking rose from 23.7% → 28.8% (+5.1pp).
For properties that didn't join, it dropped: 33.3% → 27.2% (-6.1pp).
Translation: the campaign activated inventory that wasn't selling before.
2) Average bookings per property rose
Participating properties averaged 14.4% more bookings during the campaign vs. the pre-period.
Non-participants saw bookings drop ~3%.
Bottom line: joining the campaign didn't just help properties that were already selling — it pulled in properties that weren't. And for those already moving inventory, it amplified sales.
The data is unambiguous. Korea Grand Sale delivered for participants.
