FAQ

How do you say it's a surprise on an invitation?

Put "Surprise!" or "Shh, it's a surprise" at the top, and repeat it near the reply line. Add the time the guest of honour arrives, so guests know to be early.

How early should guests arrive at a surprise party?

Fifteen to thirty minutes before the guest of honour. Give guests the earlier time and keep a lookout ready.

Who should host a surprise party?

Whoever can keep the guest of honour busy or away on the day: a partner, a best friend or the family. Someone else can handle the invitations.
