Incheon airport stopover landside

[Duffa]

Hi all
Have booked 1 night at the Grand Hyatt Incheon at the airport next week for a 14 hr layover (7pm-9am)

My question is about queues and customs, security on way back in.
Obviously we will only have hand luggage so no check in required.
Can someone please advise me on times/possible delays for security and passport etc??
Flying J so can use the lounge if we get airside too quickly.

Thanks for the "like" cm!

What airline. What destination probably helps.

My one and only experience with ICN flying Korean to China was checkin and security being pretty quick (for an 11am departure).
