Yes! DCL and Chase are really bad about communicating how it works. It took a few times to understand. It will come up on the statement and appear that you have to pay for that month, but when you look towards the bottom, it'll say the 0.00% APR costs associated and you'll have to do some math when paying the credit card as to not accumulate that crazy interest price and make it not really worth it.
Another thing to note is the 0.00% APR applies to a lot of things, but not everything. For instance, it doesn't let you wait 6 months to pay off the
disney cruise bus to the ship. It's usually packaged deals like a my way vacation package at the park or the disney cruise. One awesome way to use the 0.00% APR for 6 months is to pay off those tips ahead of time and create an onboard account with money from the card that you can prepay. I've heard other people have done this and it means you're palo and remy and drinks all can be paid for 6 months later! It's a great tool for budgeting!
Remember to rack up those points! I'm almost at 500 points I plan to use for Remy! So exciting!
