What fabulous bridesmaids you are! The bride will love you forever if you whisk her away for a girl's weekend of fun and friendship. I have two suggestions for destinations and themes:
1. Weekend in the Big City. Yes, girls, head to NYC for a shop-till-you-drop weekend. Hit all the fabulous New York shops and boutiques and help the bride shop for honeymoon finery (and summer necessities for yourselves!). Catch a Broadway show, book a table for dinner in a chic restaurant, see who can get the best deal on the sexiest pair of shoes, etc. You know, all the usual girls on the loose in New York kind of things to do.
2. Spa Weekend. Since I am not familiar with the Boston area spa scene, do a little online research, or ask around, for great spa getaway deals. One great source is SpaFinder.com, a fabulous resource for connecting people with their desired spa experience. A weekend of pampering is ideal for a bride-to-be, just what she needs to de-stress: sauna, massage, manicure, pedicure, facial, aromatherapy, etc.
Whatever you decide to do, I'm sure the bride will be thrilled to be able to spend time with her dearest friends.
