I went to my CP with relatively high expectations, but also with the attitude that I will get out of it what I put in to it. Never once have a regretted my decision to do a CP, in fact it might have been one of the best decisions I have made.
And yes I know that some people have a bad time, some people are just so-so, and some love it. I feel I got lucky. I loved most of my roommates, I loved where I worked, and I loved the people I worked with. I even went seasonal when I left because I did not want to let the experience end.
I think it would be worse to wonder what could have been, than to go down to FL and decide working at Disney isn't for you and that's that.
