seems the bride is some alternative hippie or a disorganised total dummy.
not providing food for your guests on Friday night is ridiculous, in the middle of nowhere!
she doesnt seems to have the priorities right: she is worrying you might be bored. How about worrying you might be hungry?
to be honest, I would expect her to organize some pick-up from the airport, I in her place would ask some of the family members with car to pick you up and not have you to take 3 train changes and 40 min taxi!
On the other hand, it sounds very unlikely you have to change trains 3x and get a taxi for 40 mins, I think it would be better if you research a bit more. Try to find Flixbus (very popular in Europe and cheap), dont bother with trains, bus is much better
Not providing tons of food and drinks for the wedding guests is quite unheard of in central Europe.... even for Germany....what nationality her husband is? maybe he is controlling her and resent you 2 coming? she seems useless
I would:
- excuse myself and not go
- search for more convenient transport to the place (3x change of trains IS bonkers)
- call the place (the barn) and ask how far away is the nearest supermarket, what time it closes on Friday, what time it opens on Saturday, if there is some kind of food delivery (like pizza delivery from the nearest town), if there is a kitchen/kettle/pans available, if there is a taxi service they use, etc (you said they have an internet page)
- let her send you some links to the area and contacts to the other guests, so you can ask about where they are staying, how they sorted this out (it should be the useless bride´s initiative tbh)
- dont go
I think you need to do more research re: the transport and the barn/area before you panic (given the bride is totally useless and clueless)
if you tell her (them) you have to have 3x train change and 40 mins of taxi, they will think you are an "entitled UK guest" who cannot research properly..... I just think its very unfair of them to let you and your friend to do all the research when some links would be very useful from her..... and also very unfair to ask you to be bridesmaids and then let you fend for yourself, ridiculous and tbh insulting (given you are paying everything to be there)
you are going to a bloody wedding, not an alternative hippie convention fgs!
I would not go
you dont need this kind of friend
just excuse yourselves
I think you dont see each other frequently and she may be a totally different person now from what you remember
cancel it, I would (emergency in family, etc)
dont go, imho
