So a few weekends ago my three bridesmaids were all in town to shop for dresses and have some quality bonding time. Of course the subject of the bachelorette party came up. My best friend from high school raised the subject and asked me if I wanted one. I responded that I thought it would be fun but that I would be ok without one. She was pretty clear that we should do something big, like a trip to Vegas.
She proceeded to mention it four more times during the course of three days, joking that my MOH (my younger sister who is twenty, still in college, and has limited funds compared to my other two BMs) should get to planning it right away. A few days after everyone left, she sent us all an email reiterating that we should get the planning done sooner rather than later (although any activity wouldn't be until next March or April). She even asked me if I could start checking out hotel deals.
I guess my question is how do I let her know that while a bachelorette party would be fun and I would appreciate time with all my bridesmaids, I am not going to plan my own party and my sister shouldn't be left doing it entirely on her own. I am not demanding a party - I am perfectly happy going without and honestly can't really afford a weekend in Vegas right now - but I would like to be perfectly clear that in my mind, if the bridesmaids want to do a party/trip, they need to plan it together and leave me out of it for the most part.
Am I being unreasonable?
