Treating your mom to a big milestone brunch is all about getting the details right without stressing over the bill on Sunday morning. Since off-peak venues book up faster than you think, starting a couple of months out gives you the pick of the best tables and seasonal menus.
A typical private or semi-private group brunch lands around $600. Using a tool like the Citi Simplicity® Credit Card lets you lock in deposits early and clear the balance over time.
Remember that a 0% interest window is a payoff deadline, not free money. If you still have a balance when the 18 months end, interest kicks in on whatever is left, making your mom's brunch much more expensive.
