Before buying a nonrefundable performance, check the arrival day and hotel cancellation terms. If the operator has not released your date, record its official calendar and a substitute activity rather than treating an absent date as sold out.
Eight weeks: settle the constraints
Check passport/nationality/date requirements before nonrefundable commitments; note that authorization and arrival declaration differ.
Fix flight dates, usable nights, number of bases, mobility needs and party room requirements.
Make a shared list of must-book items and cancelable items with the person responsible for each.
Compare before you commit
| When | Action | Evidence to retain |
|---|---|---|
| 8 weeks | Eligibility, dates, trip shape | Official eligibility link and checked date |
| 6 weeks | Room and base | Occupancy and cancellation confirmation |
| 4 weeks | Limited-capacity bookings | Operator calendar and fallback |
| 2 weeks | Airport, connectivity and payment | Saved route and Korean address |
| 3 days | Arrival declaration if required | Official submission record |
| Arrival day | Choose live onward connection | Terminal and actual departure |
This comparison organizes the decision. It is not a guarantee of availability or an individual price quote.
Six weeks: choose a workable accommodation base
Reserve a room whose actual occupancy and bedding fit the group, preferably with a cancellation deadline you understand.
Ask about late arrival, lifts, room type, crib/extra bed and accessible bathrooms where relevant.
Record cancellation timezone, total payable price and whether payment is taken now or at the hotel.
Check the operator: Korea Immigration Service: e-Arrival Card filing guide · K-ETA official notice: temporary exemption extended through 2026.
Four weeks: track priority bookings
For a limited-capacity attraction, follow that attraction’s official booking notice and calendar. Different venues release reservations on different schedules.
Verify current rail booking rules from the live operator; late-2026 policy changes make old one-month advice unsafe.
Keep a fallback for each scarce booking, such as a daytime palace route or an untimed museum visit.
Two weeks: join the practical pieces
Choose airport transfer and a backup, save Korean addresses and confirm arrival instructions.
Arrange appropriate connectivity and independent payment methods; check device compatibility with the provider.
Put bookings into a day-by-day board, leaving transfer and rest blocks visible.
Final week and three-day window
Recheck forecasts, closure notices and any changed reservation messages.
If required, submit the free e-Arrival Card only within its official three-day KST window using the official website.
Share key confirmations and accommodation details offline with the travel party.
Arrival and during the trip
Use actual terminal exit time to select transport; do not chase a missed final connection.
Notify the property using its published contact if arrival changes substantially.
Review next day's hours and weather each evening; the checklist is a changing plan, not a static certificate.
