Since the seats were on the 2nd floor of the Jamsil Indoor Stadium, I thought the venue was small and it would be close to the stage, but since they were stand seats, it didn't feel as close as the arena seats.

After all, I wonder if aiming for ground seats would have been worth going all the way to Korea.

GT Tour has quick replies and clear instructions for meeting points, so I was able to use it with peace of mind.
