Turning 60 is a big deal, and a private dinner is a great way to mark it. The secret to pulling this off without a headache is starting two months early so you have enough time to scout venues and secure a date.
You are looking at about $1400 for a quality private room experience. By breaking that total into small, manageable chunks, you keep the celebration focused on the milestone rather than the cost.
Remember that the 0% intro APR is just a window of time to pay down your balance interest-free. If you still have a balance remaining after the 15 months are up, the bank will start charging interest on whatever is left.
