My wife got a text message. SK Telecom (SKT) had run a lottery among customers who'd been with them for 10+ years, and we'd won. The prize: renting out Lotte World overnight, just for winners like us. All three of us went.

Quick Answer
- This was "T Long-Term Customer Adventure Day," an event run by SK Telecom for subscribers of 10+ years, age 14 and up, selected by lottery through the T Membership app.
- Winners and their families got free access to Lotte World's indoor (Adventure) zone from 11 PM Saturday to 5 AM Sunday.
- A venue that normally sees 15,000–20,000 visitors a day let in only about 3,000 people that night, so we could ride all 11 attractions without lines.
- Beyond the rides, there was a stamp rally, a dice roll that determined a discount on next month's phone bill, and extras like snacks, energy drinks, and glow headbands.
- There's a refundable deposit of 20,000 won per person — it looks like a way to discourage winners from no-showing on an overnight event, and you get it back in full once you show up.
1. So What Exactly Is This Event?
The official name of the event is "T Long-Term Customer Adventure Day." It was part of a broader 2026 customer-appreciation campaign by SKT, which also included a fine-dining tasting event called "Table Day" and invitations to a musical.
- Eligibility: SKT subscriber for 10+ years, age 14 or older, active line
- Selection: Lottery through the T Membership app (not first-come, first-served)
- Event hours: 11 PM Saturday to 5 AM Sunday
- Scale: Lotte World's indoor zone, which normally draws 15,000–20,000 visitors, let in only about 3,000 people that night, winners and guests combined
The numbers alone tell you what this meant. Less than a fifth of the usual crowd, in the same space — which means the lines that usually come with a theme park basically disappear.
2. From Winning to Walking In
The process after getting the winning text was simple. We picked up wristbands on-site on the designated day, lined up in order, and went in at 11 PM.
Parking needed some planning too. The Lotte World parking lot was open from 9 PM to 8 AM the next day, and cost 4,000 won. That price is low enough it's basically an event-day rate.
3. First Find: Battlegrounds World Agent
Right after we got in, we rode the carousel first. It wasn't bad, but honestly, a little underwhelming. Looking around, we found an attraction called "Battlegrounds World Agent" — an officially licensed attraction themed around the hit game PUBG (Battlegrounds), exactly as the name suggests.

You fly in toward an island, get shot down, land on the ground, and rack up points shooting enemies with a gun. In the later stretch, you ride a vehicle while firing. Your score gets revealed at the end.
We waited about 30 minutes and rode it — genuinely fun. But as the night went on, I noticed the line for this one kept getting longer. Good thing we rode it early — even at an event with a capped headcount, the popular attractions still end up with a line eventually.
4. The Hidden Gem on the 4th Floor: Pharaoh's Fury
Riding the World Monorail around Lotte World, we spotted "Pharaoh's Fury." I'd been to Lotte World plenty of times before, and I didn't even know this thing existed on the 4th floor.
It's an attraction where you ride a jeep, trying to escape a pharaoh's curse. The wait alone was 2 hours. But it was worth every minute of it. There are two near-vertical drops of several meters in near-total darkness, and the thrill was incredible. The whole family loved it. Even my daughter, who normally can't handle scary rides, had a blast on this one.

5. The Twist on the Water: Sinbad's Adventure
Next up was "Sinbad's Adventure." Similar concept to Pharaoh's Fury, but instead of a jeep, you ride a boat drifting along the water. This one also had two steep-drop sections, giving a similar kind of thrill.
Both attractions share the same "escape the curse" story structure — one on land (jeep), one on water (boat) — and that contrast made for an interesting pairing.
6. 3 AM, When Your Body Starts to Give Out
The event also had a stamp rally. Fill up a "T"-shaped stamp card, and you'd get a fatigue-recovery supplement. We rode a spinning attraction to collect one of the stamps (what felt like a "plate-spinner" type ride — round and round) — not really scary, just dizzying.
The real problem was the time. Once it hit past 3 AM, exhaustion hit hard all at once — dizzy, queasy. I completely forgot I'd even been hungry. Then we got handed chocolate and Pepero, and eating those brought a bit of energy back.

It wasn't full sit-down dining, but pretty much every stall selling something quick to eat or drink was still open. Just knowing there was somewhere to grab something, even at that hour, was a quiet kind of relief.
After that, we finished up the remaining event activities, ate the supplement from the stamp rally, and bought my daughter a tornado potato. By 4 AM, we decided we couldn't push any further and headed home. It was exhausting, but genuinely fun. It was my daughter's first all-nighter ever — she slept until 3 PM the next day.
7. What This Event Reveals About Korean Telecom Culture
Here's the full list of side perks built into the event:
- Ride stamp rally → complete the "T" shape, get a fatigue-recovery supplement
- Dice roll → discount on next month's phone bill, based on the number rolled
- Free chocolate and Pepero
- Free high-caffeine drinks
- Glow headbands, event tote bags
Looking at all of this together, it's clear Korean telecom companies do a lot more than simple rate discounts to keep long-term customers. They're combining gamification (dice, stamps) with large-scale offline events (renting out an entire theme park) to offer something money can't quite buy — an experience.
FAQ
Can anyone apply for this event? No. You had to be an SKT subscriber for 10+ years, at least 14 years old, and winners were chosen by lottery through the T Membership app. Applying doesn't guarantee you a spot — you need luck too.
Is it completely free if you win? The event itself (admission, rides, snacks, etc.) was free, but there's a refundable deposit of 20,000 won per person. You get it back as long as you show up, but it's worth knowing that winning doesn't mean 100% zero cost. Parking (4,000 won) was also a separate cost.
Do events like this — renting out an entire theme park — happen often? Not often. A major telecom company renting out an entire theme park exclusively for long-term customers isn't a common occurrence, and that's exactly why it made news.
Conclusion: What Happens When You Stay Loyal
Staying with the same carrier in Korea for 10+ years doesn't mean you'll win an event like this every time. But one thing became clear through this experience — Korean companies go a lot further than you'd expect to hold onto long-term customers.
3 Things to Try Today
- Check your carrier's membership app to see if there are any long-term-customer event notifications.
- If you win an event like this, check the entry conditions in advance — deposit, what to bring, and so on.
- If you're joining an overnight event, pace yourself — exhaustion can hit hard and fast around 2–3 AM.
3-Line Summary
- I won a lottery through SKT's "T Long-Term Customer Adventure Day," an event for 10+ year subscribers that rented out all of Lotte World and opened it free from 11 PM to 5 AM.
- With far fewer people than usual let in, we rode popular attractions like Battlegrounds World Agent, Pharaoh's Fury, and Sinbad's Adventure with little to no wait.
- Extras like the stamp rally and dice-roll phone bill discount rounded out an experience that says a lot about how Korean telecom companies manage long-term customers.
