I arrive ICN on Oz 736 from SGN at 6:45 Am and depart same day on Oz 202 at 14:50 to LAX. That's approx. an 8 hour layover. Our tickets are in J from SGN then F to LAX on the A380.
I have booked a room at the Grand Hyatt Incheon and have a few questions:
1) Will it be any problem with immigration or customs to leave the Airport ,go to the hotel to shower and rest and then return?
2) If no problem am I correct that no visa is required?
3)Assuming I leave the airport for the hotel is two hours enough to plan to be back at the airport prior to our flight to LAX
4) Does the Grand Hyatt Incheon run a shuttle and if so where do I catch it?
