Sending a coworker or loved one off into retirement deserves a proper toast, but party costs add up fast. A weekday evening cocktail hour at a local bistro usually runs around $1,800 for drinks and bites. The trick is locking in the venue early so you get lower minimum spend requirements without feeling rushed.
If you start planning a few months out, you give yourself breathing room on deposits and guest counts. Spreading that $1,800 tab over time makes the milestone celebration painless to pull off.
Remember that a 0% intro APR is a deadline, not free money. If you still carry a balance when the 18 months end, the standard interest rate kicks in on whatever is left, making your event much more expensive.
