Be careful of the 6 month no interest promotional deals for Disney Visa.
Some folks here have said they have made a purchase utilizing the six month promotional deal. They continued to use the card for other purchases. At month end, they paid for the other purchases, but the Credit Card applys payments first to promotional offers. So they wound up paying interest on the other charges. If you are not going to put anything else on the card, then the promotional offer might be okay. Call them to verify how payments are applied, as they may have changed.
Also Disney Visa has a higher interest rate than other 'no annual fee' cards. If you pay in full every month, then no worries. However, if you don't pay the full amount, you might be better to find a lower interest card.
With all that being said, we use our Disney Visa for everything, and have been able to 'earn' part of the deposit for an upcoming cruise.
