Fingers crossed that all goes well followed by speedy recovery.
If you are driving, stop worrying... bring the 24, but leave the box of 72 in the car... you can always run to the parking lot if you find yourself longing for more.
May wish to bring a cafeteria tray to put all your stuff in one place and not forget anything behind at the end of the day... also your pencils won't be roaling all over the place. You can even draw in the tray on your knees, if the first day you don't have access to a table.
Good luck!
