Advice on what to do concerning bachelorette party

So I’m a bridesmaid in my friends wedding. The bride asked her sister (18) to be her maid of honor and plan her bachelorette party. Bride noticed 2 months ago that MOH hasn’t started planning and she was worried about it (this bride DESERVES special, she has overcome a ton and she really does deserve special) she asked me to check in and see if MOH needed any help. I agreed, I reached out, I asked MOH if she wanted help, we messaged back and forth 3-4 times about what the bride would want. I know this bride very well she loves summer, the beach, cheesy stuff, like go all out special. Well my frustration has grown because this MOH still hasn’t planned anything, she ignored me for the past 2 months, so maybe she didn’t need help anymore? Well, I got in contact with the bride and checked in if she’s heard anything, she hasn’t and is going to ask MOH to talk to me. So I reached out to the MOH again, she has nothing planned or even started. This wedding is in September, beach houses fill up FAST here so I’ve been researching, found an affordable one. And messaged about what else I know the bride would love (decorations, goodie bags, food) and shes not responding to me again. I’m ready to just plan this thing without the MOH but don’t want to be disrespectful, I have a group chat going with the other bridesmaids and the MOH to get a date set, t-shirt size, who is coming, any allergies, and I said if anyone can help financially, that would be great but not mandatory. MOH didn’t even look at the messages.


Do I speak to the bride? Do I just plan it and tell MOH where and when?? We have to get this place booked ASAP before we loose our spot. I think the MOH may just be a little young to plan something like this considering she can’t book an Airbnb on her own, she can’t buy alcohol, and probably not very financially stable, which is all OK but she really should say something, ask for help, just tell me to plan it, or just respond to me.
