how long are ayu's concerts?

[Kei Rei]

soooo i'm studying abroad in japan for this year and you know, being a hardcore ayu fan, i had to buy a ticket. it's amazing, just imagining. i've been waiting for this for the last eight years and it's finally happening, i can't even believe it.

but anyway. i need to know how long her concerts typically run, particularly the HOTEL LOVE SONGS/POWER of MUSIC tour, as i may have a conflict with a school event the next day, and i need to plan train schedules and such~

(i'm going to the 9/30 in osaka btw, anyone else going? )
