Before You Go
Book KTX or SRT tickets from Seoul to Busan at least 2 weeks ahead — August seats sell out fast.
Reserve domestic flights Busan (PUS/Gimhae) to Jeju and Jeju to ICN well in advance; prices spike in August.
Pre-book a Jeju rental car online — airport desks run out of automatics during peak summer season.
Load a T-money card on arrival at Incheon for all Seoul and Busan metro and bus travel.
Check Seoul Station luggage storage hours and locker sizes online — large suitcases need staffed storage, not coin lockers.
Good to Know
Taking KTX immediately after a 12-hour flight is doable if you land in the morning — afternoon arrivals risk exhaustion, so Day 1 in Seoul is the safer play.
For Busan vs Jeju nights, the 3/2 split (3 Busan, 2 Jeju) is better — Jeju needs a car and is tiring; 2 nights is enough without rushing Busan.
Store non-essential luggage at Seoul Station coin lockers on Day 3 and retrieve on Day 7 — it's safe, cheap, and frees you up for Busan and Jeju.
August in Korea and Japan is extremely hot and humid; schedule outdoor sites before 11 AM and after 5 PM whenever possible.
Japan (Tokyo) doesn't appear in this 7-day route — if you're adding it, a separate leg via Fukuoka from Busan by ferry is the most logical insertion point.
Kakao Maps outperforms Google Maps in Korea for transit routing — download it before you leave home.
Convenience stores (GS25, CU, 7-Eleven) in Korea are genuinely excellent for fast meals — don't overlook them for breakfast or late-night snacks.
