hope someone can help me here ...

my return flight from korea is 11pm .. so i guess i need to be at airport around 9pm. but i have to check out my hotel at 12noon .. so my problem is what to do if my hotel don't allow me to keep my bags ?

i will be staying at Uljiro Co-op Residence. anyone stay here before ? i read the review quite good.

for this trip, i plan to try their city bus tour .. just like KL hop on .. so i didn't book any tour.
