"An hour drinking champagne in the afternoon is not appealing to you? Are you teetotal?"
Hahahaha. I'm writing this while swigging sherry (sadly true).
No, I'm not teetotal, but I've been to a LOT of weddings and similar events. there is never enough booze or canapes going round.
"There won't be any boring people invited, the guests all know each other so it's a 90 minute meal with friends."
What, literally? All of your university/school friends know the groom's great-auntie, do they?
"I love speeches. They're a chance to talk about what the couples relationship is really about I find them moving and entertaining. And if you were offended it's only half an hour to grit your teeth through."
You asked what people would dislike. I answered truthfully. People hate this. Why on earth would you think that loads of people want to/ought to/have to listen to 30 minutes of public speaking about you and your husband-to-be and "what your relationship is really about"? Do you really not find that the most unbelievably cringey and narcissistic thing imaginable?
"The DJ is great and we are putting the playlist together ourselves."
Yeah, that's the music YOU like. Not the music all of your guests like. I'm not self-centred enough to think that anyone should be subjected to my particular mix of Aphex Twin, the Chemical Brothers, Blur, Bjork, and Bach, so why would you think that anyone wants to listen to your 'my best choonz' playlist?
"Oh- and we aren't going to invite anyone dead set on hating every single second of a joyful celebration so cheers! wine"
And here we have the crux of the matter. It's not "a joyful celebration" to anyone except you, and perhaps your parents if you have that sort of parent. To everyone else it's a Saturday/Sunday crossed off the calendar and a few hundred quid out of the bank account.
