I used to work for Disney World park in Orlando US. The schedule is tight. Sometimes between 2 shift you have only 8 hrs to sleep. Waking up, eat small breakfast then go to work. Now in my motherland Im unemployed. Maybe somedays
At my job we used to have to work 18-, 19-, or 20-hour shifts regularly. My record was 22.5. Really sucked. Thankfully we've made some policy changes so the worst I'll get now is probably 0830 - midnight, but it's risky.
