Planning hen party with little help from other bridesmaids?

[ThankYouFish]

I’m looking for opinions as I haven’t been a bridesmaid since I was a child and therefore first time being part of arranging a hen party.

I am maid of honour for my best friend, there are 2 other bridesmaids (one is a close friend, the other Ive met before but don’t know well) . All the same age.
Hen party is for 16 people. I was lucky in that the bride gave me a loose idea of what she’d like.
The hen party is in 2 weeks, it’s an afternoon/evening event.
I have planned it all, including buying decorations, with almost no help from the other bridesmaids. I have asked their advice on a couple of things, which they both did give answers (although a little vague) but at no point have either of them asked how the planning was going or if there was anything they could do (even when a couple of other people were being difficult with the choice of venue).
I was so pleased to be asked to be maid of honour and more than happy to plan it. I also fully appreciate they both have other things going on! But now that it’s nearly here I’m just a little annoyed that neither of them have offered to do anything. Is it normal for the bridesmaids to help more or is it usually all down to the MOH?
YABU- bridesmaids don’t help, this is normal
YANBU- bridesmaids do normally help out more

Is it normal for the bridesmaids to help more or is it usually all down to the MOH?
There is no normal, just lots of different experiences and expectations. I always thought it was for the bride to crack on with organising if she wanted to do something. I didn't ask my bridesmaids to do anything about it, didn't think it was their job. Maybe the other bridesmaids in this case feel similarly.

I don’t think there is a normal. I would say that a lot depends on how well all the bridesmaids know each other and that if they are not already good friends then it’s more likely that it will not be a joint effort.

Other than that it’s dependent on what else they have going on in their lives and personality type.

Did you specifically task them with something? Generally in life when organising anything , one person takes the lead as chief organiser and the others are then asked to do certain bits, otherwise it wouldn’t work, so not sure why it would be different in this situation. Also, people like to help, but won’t know you need it unless you ask.
