Hey Engineer, like others said, it does get easier, even in your second week. I was so nervous when I went on the Vacation Planner (aka ticket sales) window at
Disneyland, but you soon get the hang of it. I was so scared my cash drawer would be off too, but counting back gets to be secondhand after about 3 transactions. If there is a problem with the cash, you and your lead can go through the transactions to see what went wrong, and fill out over/short forms so its documented. I got called up to the manager's office twice for different things, where they told me what I did wrong so I knew not to do it that way the next time, and believe me, I never did it wrong again!
As for sick days, I'm sure its roughly the same at World, but if you called in sick, you got 3 points on your record, and could only have up to 21 or so before you got kicked out. Just don't call out and then go to the park, because like someone said above, that will also get you an immediate discharge. You can take a personal day, just make sure you don't go anywhere near the park.
As for costumes, I once decided to wear the honey mustard dressing on my Main St. top instead of using it on my chicken nuggets, and with 10 minutes before I had to clock back in, I ran to Costuming, got a new shirt, and made it back to my clocking location with 2 minutes to spare. Granted, this was Disneyland, and Costuming wasn't too far away, but the moral of the story is, don't fret it. Just do your best, give 110%, just remember that the guest in front of you probably doesn't realize that the 3:30 parade is at 3:30, and you'll be fine.
