Standing for 6+ hours working. If not at the gate or a spot with a view there is big possibility of becoming bored and daydreaming.
Don't always get to choose your position. You need to sometimes ask the specific supervisor or administrative staff to get the right spot. Most of the time just ask the pass distributor for the number. Not guaranteed.
Break rooms can be far away and hard to get to with the crowds.
Some supervisors give 30 some give 45 for break. Either way, the breaks always FEEL short because you are weaving in and around people and running back and forth.
On the supervisor side, it can be easy. However, new employees require reminders and bad employees require constant supervision. Those are really the only two things. What goes and what doesn't is at your discretion and what happens is your accountability.

New people makes having a consistent friend group difficult, many acquaintances
Not as bad as some retail, but still patrons will pressure you in different ways including belligerency, rule bending, storytelling, feigned ignorance, deliberate ignorance, bribery, etc. just to name the common ones.
