A friend asked me to go on a long weekend break to a popular city abroad, to a place I've always wanted to visit. She knows the city so said she would book the hotel and we both booked our flights individually (on same flight). Hotel paid on arrival - no cancellation fee.
It's in 3 weeks time and I asked yesterday for name of hotel and whether our rooms would be near to each other and other details. To my surprise she told me it was one room and we'd be sharing. This didn't even occur to me, I'm in my 50's and not shared with anyone (apart from ex partner) and have no wish to do so. I like my own bathroom, plus I snore and I often wake in the night to make tea, read etc.
I asked friend if we could book 2 rooms but this would double the cost and she said she can't afford it. I suggested we swap to a cheaper hotel but she doesn't want to do that as likes the hotel she's booked.
She has asked that I don't go and she takes her sister instead. However flights have gone up in price and she feels it's only fair if I reimburse her sister the cost difference between the flight prices, as it's my choice not to go (her words). But I would also lose the cost of my flight as that's not refundable.
I have said I could still go with her and her sister but she's pissed off with me and not responding to my calls or texts, so don't think that's an option.
She can't understand why firstly I won't share and secondly that I'm being difficult in not accepting her alternative plans.
I'm wondering if IABU (although it would really spoil the break for me to share). I also do t think I should pay sisters costs but am I in the wrong?
