When I flew OZ SIN-ICN-JFK in Y, OZ provided a day room in one of the Inn at a nearby town in ICN. Later I found that it is available to all Y pax, once, either outbound or inbound, but not both ways. So, on the inbound I decided take a ride on the KAL limousine, heading to Lotte World to spend the day. Come to think of it, it was enjoyable ^
