Wehn making your guest list for the bachelorette party, you should focus on memories or meaning rather than going big. What is going to make this party memorable(in a good way) for the Bride? Should you invite EVERYONE she knows or just a few close friends. Mom? Grandma? Super gossip Aunt Sally? The most common size we see for bachelorette parties is 8 to 12 people. Beyond 12 it becomes more difficult to manage, to plan, and make decisions. Larger parties can be fun but make sure you’re doing it for the right reasons.
