Hi, just look for some advice!
I had my hen party recently - organised originally for 10 of us, 1 dropped out early one - two dropped out the day before and on the day. The first had a good reason, the second not so much.
I'd asked my MOH to plan, and while she's lovely and wanted everything to go well - planning is not her strong suit. Early on I made sure she'd got a date picked (created a Doodle poll for her and looked over her shoulder while she sent the message to the group) - but after that I relaxed, I told her just to make a smaller group with a few other bridesmaids who liked to plan, and let them do most of the work. But she's so reluctant to ask people for help (to 'bother them') I found out later she didn't do this. A month away from the date of the hen party (the hen party date was booked in a year in advance) I start to get messages from bridesmaids and other guests letting me know nothing was booked and they were starting to worry. MOH wasn't replying to their messages - I spoke to her and she was completely frazzled. She didn't want to 'bother' the others, but couldn't plan it herself. So I, essentially, took over, but secretly, because I knew if the others knew what I'd done my MOH would feel embarrassed, like she'd failed. So after a long week of back and forth - struggling to find things to do that hadn't been booked months ago (I warned her it was going to be a busy year for hen parties) I eventually found us some things to do - not my ideal hen party, but fine - I figured we'll get drunk it'll be fun. (and some might say - why give her that job if you knew she wouldn't enjoy it - she raised it first and I knew she'd take offence if she wasn't allowed to plan it).
I give her a list of things to do the day before - she's setting up in the airbnb (which is in our hometown) - and long story short she's said 'no' to help from the other bridesmaids, realises she doesn't have time to do it on her own, so I'm called in - getting the groceries, blowing up balloons, making sandwiches...really irritated but don't want to say anything because I know MOH already feels awful.
On the day - two bridesmaids are late - one by an hour and a half so she misses all of brunch. One is in a foul mood because she's hungover. We move on from brunch to cocktail making - we finish up after 2 hours in cocktail making and we're supposed to head back to the airbnb for games, food, etc. If I'm honest, the airbnb bit was the bit I was most looking forward to. Three of the bridesmaids ask to stay behind for a few minutes to finish their drinks (they had a tiny bit left, we only had two drinks each) - I say fine, but hurry up! An hour and a half later they finally come back - drunker, having clearly stayed for at least one more drink, and then gone to the shops to buy more drinks (we had plenty in the airbnb). They're so drunk that they're basically passing out and we've only done half of the day. One starts talking about going home early because she's drunk too much. At this point I'm so upset - I've had to plan my own hen, make the food, hang the decorations, etc. and now half the group disappears for almost 2 hours. I go upstairs and text my MOH to tell them I'm not well and they all go home. It might sound childish, like I was throwing a tantrum, and I probably was...lol...but I just feel so upset and so deflated. There's talk of throwing a hen party part 2, but I honestly can't think of anything worse 
Obviously I'm venting, but any advice??
