11 Common Bachelorette Party Blunders

To make everything easier, from decorations to favors to outfits, try to unify the trip with some kind of theme. Step outside the box by choosing the bachelorette's favorite decade, hobby, colors, or holiday — Mardi Gras, anyone? Keep the theme in line with the couple's interests by choosing, say, a music motif for concert lovers.

Large groups can be tough to coordinate, so be sure to plan out every last detail — especially transportation. Make reservations several weeks ahead of time and send detailed itineraries to guests so that everyone knows what's expected of them ahead of time. If it isn't a jam-packed weekend, go ahead and mark down the free time, too, so that girls can pencil in their own plans.

Steer clear of astronomical, unexpected costs by deciding on a group budget beforehand. Reach out for guests' opinions and come to an agreeable consensus on how much you plan to spend. There are bound to be a few discrepancies, but go ahead and make plans according to the majority vote. It doesn't have to be all or nothing, either. For those who can't afford to join in on all the festivities, let them pick and choose which events they'll be able join.

What happens in Vegas stays in Vegas . . . unless it's all over Facebook. Steer clear of any 2 a.m. Instagram snaps that you might regret in the morning, and chat with the group about what is or isn't appropriate to share on the Internet. If you want to share some funny shots with the girls but not with the bachelorette's soon-to-be mother-in-law, ask the guests to email you their photos, then send out a CD of all the compiled pictures.

Tiaras, light-up rings, sashes, matching tees — needless to say, it isn't tough to spot a bachelorette party. If you're not careful, all that attention can also be a target, so keep the group safe by turning down any drink offers from friendly bachelor parties or random guys. A good rule of thumb: as always, be sure that you see all the drinks that are made for you.

A great way to get the bachelorette's future husband involved is to play a fun, simple question game. Ask him a series of questions about both himself and the bachelorette, then ask her the same questions over the weekend to see if their answers match. He'll be happy to know that he has some sort of presence throughout the festivities, and she'll love that you incorporated her husband-to-be.
