Like the titles says really. And hen dos too. I resent paying premium prices, to stay in poncy hotels when you're a wedding guest, but most of all for the kinds of relatives you see twice a year tops. I'm happy to give a pressie, but not so much with the hotel bill. If you dont fork out for the hotel room, people think you are either too mean, or too poor.
So, I am planning to get married in a cave. DP is totally up for this and it must be possible.
My DM thinks it is a terrible idea. She says caves can dark, dank and they are unpleasant places. l like caving and it is beautiful underground. My DM has asked me what people should wear - wellies? I replied that if it works for them, they can wear what they like. She asked if I would wear a wedding dress with a pair of wellies. I replied that it was a distinct possibility. We haven't told ILs yet.
AIBU to get married in a cave and AIBU to derive an evil pleasure from being a bridezilla who will also mildly exact revenge upon all the people who have made me stay in poncy hotels when I didn't actually want to for all these years?
I also intend to get married in a remote location and hire a "down to earth" place for the reception and guest accomodation. they'll attend a wedding in a cave and hopefull stay in a Welsh pub/B&B in the middle of nowhere - deal with it mofos, it's my turn to be bridezilla. 
By the way, as the bride, I shall also do my own speach and will keep my own surname. Bollocks to convention.
