Am I being mean to do a trip with one friend and not the other?

[WilmaFlintstone38]

I live in Yorkshire. I suggested to two friends who often do this sort of trip that we go to the Biba exhibition in London this September. One friend lives nearby, the other woman lives in Wimbledon. My local friend said she'd love to but she can't really afford it and as she's disabled she'd find it difficult and exhausting. I know she's not making excuses.

I really want to do it (though it's costly travelling) so do you think it's not very nice if I went and met my other friend? It feels like I'm excluding my local friend and feels a bit mean but we'd really like to go. I've not discussed it with either of them yet.

WWYD?

Your friend has already said she will find it too much so I think you are justified in still going. You can't stop doing things because she would find it difficult and exhausting. Maybe think of something else nearer to home which you can do with her at a different time, which wouldn't be too tiring and that she could afford.

Go on your own!

She's already said she would find it too much.

Why not go, buy the book of the exhibition and some postcards from the shop, and arrange to take lunch over to her (or out for lunch if she's up to it) afterwards?

Go.
Can you not arrange another putting with the friend doing something else?

Go. You can't live your life not doing something because someone else can't for any reason.

If we all did that, no one would ever do anything.

You invited her, she gave her reasons for saying no and so it's fine of you go and do it with your other friend. Ask her if there's anything else she'd like to do and arrange to do that too.

I’d still go. You offered she declined. Let her suggest a trip for next time

Blimey I thought you were going to be a group of three friends and you were only going to ask one of them to go and exclude the other. This has happened to me and I was really upset about it.
However this is clearly not the case. You have asked her and she said no, so go with your other friend.

If I was your friend, I'd feel terrible if you didn't go because of me.

If you don't go, it won't help your friend in any way. Both of you (actually all three of you) won't have seen it. Whereas two of you can go and enjoy it.

You've done nothing wrong. Go and enjoy (and as a pp said, maybe buy her a nice gift relating to the exhibition so she knows you were thinking of her).

I'd go anyway, and maybe buy a couple of little treats for her.
