I have worked there for a year and have been accepted to work another year. I too have problems with starting situations off on the wrong foot; however, after working at Cedar Point, I can say that if you follow these simple guidelines, you will fit right in. (at least these were what turned out to be important on the Gemini)
1. Don't lie about things that you have done in the past, esp. making up fantastic stories about yourself because everyone can usually tell when you are lying and it makes you look ridiculous and untrustworthy. (I.E. the person on our ride who claimed to be fluent in three languages as well as the world tai kwan do champion--he was ostracized for A. blatantly lying to us and then B. lying to us again when he wouldn't admit the first 500 times that he was lying.)
2. Don't victimize yourself and then use it as an excuse to be lazy. This pisses off co-workers too. (Similarly, we had a person on our ride last year who complained that she had to stand up too much and that we were all against her because she couldn't sit down. This is ridiculous because she was forgetting an instrumental part of the job description, the part that says that we have to stand a lot. All she ever did before she quit was complain and use every little opportunity to sit on her*****while the rest of us worked.)
Just be honest and friendly and you will have more new friends than you will know what to do with, esp. if you like to party.
