I agree with Gary. Give them a call. Just remember, if it's an amusement park, they want you to be personable and happy, so use your call to emphasize how enthusiastic you are to help out and sound your brightest. Smile on the phone as you talk - it will make you sound happier. It's ok to call back again the next day as well to see if they need any help. Show your enthusiasm to stand out from the crowd!
