I have to say this hen do sounds like the seventh circle of hell to me.
Dear God, nothing like a bit of forced enjoyment to have you cringing from your head down to your toes and wishing you were anywhere else but there. Of course you also run the risk of Jemma shooting you a withering stare if God forbid, you daren't look anything but overjoyed at the rapturous experience she’s arranged for everyone and anyone who doesn’t toe the line will be quickly taken to one side and explained that she’s arranged all this for people to enjoy so they better well enjoy it.
Oh but it gets better, believe it or not? If being browbeaten into happiness by Jemma wasn’t bad enough there’s also the matching outfits you get to wear to the airport to look forward to.
I suppose you could only hope they’re not from the ITS range as I wouldn’t want to be in an enclosed space, let alone a plane, with all that cheap, synthetic material and the static it will generate. 
Lastly but by no means least(ly) then there‘s the posed group photo by the wedding door at Pickle Cottage. No doubt the dictator, sorry Jemma, will have that all planned to the nth degree and all. What’s the betting she’s got a plan of where everyone is to stand and the bloody hen do cold cups will take pride of place as well; never one to miss a trick is sticker sister. I just feel for the poor folks on the flight with with them all although I’m sure Jemma will just inform them they can’t be irritated by them and their behaviour as she says they’re not. I mean she is the Maid of Honour remember and in her head at least that translates to ‘Ruler of the Modern Western World’!
