From an International perspective anyway...
There were guys on my presentation who, while they didnt have long hair (i.e it wasnt even close to their shoulders), it wasn't Disney Look compliant (i.e was over the ears, below shirt collar etc.). Not sure if they got in, but *shrugs*
As for tatoos, you would need to have one that can be obscured. For instance, if it's on your back and you have a white shirt on your uniform, as far as I know, you have to wear a t-shirt/vest underneath or a jacket (or whatever) over it to ensure it's not visible. If it's on your lower leg, you wont be able to wear shorts with your costume-even in the hot Floridian summers!
Finally at my presentation/interview, all the guys were wearing suits. I chose not to wear the jacket with mine but that was perfectly ok.
Good luck at your interview!
