Hi

This is my first trip to Seoul. Am thinking of taking the redeye flight to Seoul. Flight will arrive at 530am. By the time, I arrive at hotel, it should be around 8am which is probably too early for cehck-in. What activities can I do early in the morning? Any cheap accommodation to rest for a few hours if I am dead tired? Or I should take the morning flight and arrive there in the afternoon?

Thanks.
