Airbnb CORTIS is becoming a very literal kind of K-Culture Travel: not just watching a music video or streaming a song, but stepping inside a Seoul space built around CORTIS and the title track ‘REDRED.’ Airbnb introduced ‘CORTIS’ Secret Space in Seoul,’ a collaboration inspired by ‘REDRED,’ the title song from CORTIS’s second mini album ‘GREENGREEN,’ with a three-part program spanning an Original Experience, an overnight stay, and a public pop-up. 1
For fans, the appeal is easy to understand. The project takes the visual contrast of green and red and turns it into rooms, clues, props, and missions. It also shows how K-pop travel is moving beyond concert tickets into designed fan spaces where the trip itself becomes part of the fandom memory.
Airbnb CORTIS Secret Space: What Is Happening

The Seoul Secret Space is structured as three separate formats. On April 28, Airbnb’s Original Experience was arranged for up to 30 participants, with a chance to meet CORTIS members. The overnight stay followed on April 29-30, allowing one team of two people to spend one night in the same themed space. From May 1-7, the concept expands into the ‘Airbnb & CORTIS Green vs. Red Secret Space Pop-up,’ which is designed for more than 1,000 visitors. 1 2
Because the current date is April 28, 2026, the Original Experience is taking place on April 28, while the stay and pop-up dates are still ahead. The public pop-up reservation schedule opened at noon on April 23, with operations set for May 1-7. 3
CORTIS described the invitation as meaningful for fans, saying, “It is very meaningful to invite COER to CORTIS’s Secret Space in Seoul.” 1 That quote matters because the whole project is clearly framed as a fan-first experience rather than a generic branded installation.
Here is the compact version of the key facts:
| Item | Details |
|---|---|
| Collaboration | Airbnb and CORTIS |
| Core concept | Inspired by ‘REDRED,’ the title track from ‘GREENGREEN’ |
| Original Experience | April 28, for up to 30 participants |
| Overnight stay | April 29-30, one team of two guests |
| Public pop-up | May 1-7 in Seongsu-dong |
| Pop-up capacity | More than 1,000 participants |
| Member appearance at pop-up | CORTIS members will not participate on site |
Inside the Green vs. Red Pop-Up
The May pop-up is where the Secret Space becomes accessible to a much larger group of visitors. It is built around the ‘REDRED’ concept and uses interactive zones, card keys, keycap holders, mailroom bingo, and UV clue finding as participatory elements. 3
BizEnter described the Seongsu-dong pop-up as split between red and green spaces, visually expressing the contrasting images of the new song and album. Visitors receive a card key and keycap holder, then move through staged interactive activities. 4
One important detail for fans: the pop-up does not include an on-site CORTIS member appearance. That may disappoint people hoping for a surprise meet-and-greet, but it also makes the format clearer. The April 28 Original Experience is the member-meeting component, while the May 1-7 pop-up is the larger-scale interactive fan visit. 3 2
I like this distinction because it helps you plan realistically. If you are visiting for atmosphere, photos, clues, and the Green vs. Red concept, the pop-up is the relevant part. If your main interest is a direct artist interaction, the available source material places that element with the April 28 Original Experience, not the public pop-up.
Why This Matters for K-Culture Travel
Airbnb’s CORTIS project lands inside a wider travel story. Airbnb said its own research found that 94% of travelers who had visited or planned to visit Korea said K-culture influenced their interest in traveling to Korea. 1 Korea JoongAng Daily reported that Airbnb’s ‘Korea Calling’ report surveyed 4,500 people across nine countries; 94% said K-culture influenced interest in Korea travel, and 75% identified it as a major factor in the decision to visit. 5
At a Seoul media event on April 28, Aju Business Daily reported additional Airbnb survey findings: K-culture-influenced travelers spent an average of $435 more per person than general tourists, and 88% said they had stayed, or planned to stay, at least three nights. 6
That context makes the CORTIS Secret Space feel less like a one-off fan event and more like a practical example of how fandom can shape itineraries. A visitor might come to Seoul because of a song, a group, or an album concept, then spend time in a neighborhood like Seongsu-dong through a themed pop-up. Seo Ga-yeon, Airbnb Korea country manager, put it directly: “K-pop is one of the biggest factors influencing how people decide to travel today.” 3
Sharon Chan, Airbnb Asia Pacific chief, also summed up the broader mood with the short line, “K-pop is really taking over.” 5 For this particular project, that influence is not abstract. It has dates, rooms, activities, reservations, and a Seoul location.
