Turning one is a big deal, mostly for you. You survived the first year, and it is time to celebrate. But popular play venues book up fast. If you want a weekend slot that fits around nap times, you need to lock it in at least two months before the big day.
A great party usually runs about $650 once you add up the venue rental, cupcakes, and party favors. We can spread that cost out over a year and a half so you do not have to take a big cash hit all at once.
This plan only works if you pay off the balance before your time is up. The 0% interest window is a temporary break, not free money. If you still have a balance after 18 months, the standard interest rate kicks in on whatever is left, making that first birthday a lot more expensive.
