1) would a credit card be better then cash?
It's a personal choice, but I think plastic is a lot more convenient than cash. I use a debit card on smaller purchases, since that'll directly come out of my bank account (less work for me to do in the end).
2) is there a bank i can deposit my paycheck in at wdw?
There are several banks in the area (most common external bank with branches is SunTrust), but if you don't already have an account with any of them, your best bet is to sign up with
Disney's Partners Federal Credit Union, which you can do after you arrive. To go along with the last question, Partners will mail you a debit card a few weeks after sign up.
Regardless of the bank you use, you can enroll in direct deposit or cash your check every-week, it's your choice. You can also cash your check at
Walmart (and some other area merchants) if you pay a small fee ($3-5).
3) what is a good plan when concerning money while on the cp?
Depends what you mean. At one point Disney recommended bringing between $350-400 in starter cash, and that seems like a good place to start. Keep in mind that your first paycheck will be modest, your second paycheck will be very minimal (if anything) and after that, your average paycheck (with rent and taxes deducted) will be around $140 for a 40 hour work week.
The best way to look at the program: it's a break even experience. You may be able to save some money and take it home with you, but otherwise, the costs of living coupled with the price of entertainment ends up turning the experience into a break-even one for most.
