Before check-in, have your reservation confirmation, passport or other accepted photo ID, payment method and any late-arrival instructions ready.
At the property, the main things to resolve are room availability, a separate card or deposit request, late-night access, and whether the room you receive matches the reservation.
Check the room type and bed · serious cleanliness or odor issues · hot water and basic room functions · any material feature you specifically paid for
1. Arriving Early: Ask About Luggage Storage
A confirmed reservation does not make the room available before the property's normal check-in time. Early check-in depends on same-day availability and can carry an extra charge.
If you reach the hotel well before check-in, ask:
Larger hotels commonly provide luggage storage, while small guesthouses and self-service stays can have different staff hours or storage rules.
2. Card Requested at Check-In: Charge or Hold?
Prepaid reservations can still have a separate deposit or card-authorization requirement at check-in.
A property may need to cover an unpaid balance, incidental expenses, a deposit or a temporary authorization.
Ask three questions:
“How much is the hold?”
“When is it normally released?”
As one current Korean hotel example, Grand Hyatt Incheon says guests need a valid government-issued photo ID at check-in and that a credit card or cash deposit is required to guarantee the room and incidental charges. This is a property-policy example, not a universal rule for every Korean hotel.
A temporary authorization can also remain visible for a period determined partly by the card issuer.

3. Late Arrival or Self Check-In
Small hotels, residences and guesthouses may use a door code, key box, kiosk or mobile check-in link after staffed hours.
Before a late arrival, save:
Exact address and phone number
Latest check-in time
Door code, key-box, kiosk or mobile check-in instructions
Keep the access instructions somewhere you can open without mobile data.
If a kiosk cannot find the reservation, check the guest name, arrival date, booking platform and confirmation number. A booking-platform confirmation number can differ from the hotel's internal reservation number.
If the booking still does not appear, use the staff-call function or the contact method supplied by the property.
4. Check the Room Before You Unpack
Room and bed
Confirm the room type and bed configuration shown on the reservation.
Serious cleanliness or odor issue
If there is a clear problem, document it before luggage, food and personal items are spread through the room.
Water, lights and climate
Test hot water, basic lighting and the room's main heating or cooling controls.
Features you specifically paid for
If the booking explicitly promises Twin Beds, Ocean View, Balcony or another material feature, check it before settling into the room.
Photograph the relevant condition and contact the front desk or property while the room is still largely unused.
Describe the reservation difference directly:
Keep the reservation screen, relevant property messages and useful photographs until the issue is resolved.
5. Check-Out, Remaining Charges and Luggage
The night before departure, check:
Any remaining balance or deposit procedure
Late check-out availability, if needed
Whether luggage can be stored after check-out
If your train or flight leaves later in the day, ask about post-checkout luggage storage before leaving the room.
When the property cannot store your bags, station lockers or commercial luggage-storage services can be alternative options.
6. Three Korea Hotel Details
Korean lodging businesses with 50 or more guest rooms are subject to restrictions on the free provision of specified disposable amenities, including disposable toothbrushes and toothpaste. Check the property's current amenity list.
220V / 60Hz electricity
Korea uses 220V, 60Hz electricity with round two-pin outlets. A plug adapter changes the plug shape; it does not change voltage. Check the device input label—many phone and laptop chargers are marked 100–240V.
Key-card power slot
Some hotel rooms use a wall-mounted card slot near the entrance to activate room electricity. If the door opens but the room appears powerless, look for the slot before reporting an electrical problem.
