Instant dislike

I think I'd not go.
When I've had these instant dislikes, it's turned out to be mutual & some people are stirrers & if they don't like you they'll be causing trouble. (not saying this lady is, but still)
Could you meet up with one or two of the others if there's something on you know they might enjoy?
Or go but keep your head below the parapet by not saying a lot.

I’d keep going……I wouldn’t let anyone’s presence make me feel that I had to withdraw.
Just try to avoid sitting close to her and don’t enter into any personal conversations, there’s lots to chat about without revealing private stuff surely?

Keep with the group and avoid sitting next to her. Just be polite. I trust these instincts, they are given to us for a reason and I’d bet my bottom dollar you are not the only one in the group to sense this. Keep quiet, though, not nice to gossip.

Yes, keep going for a few more sessions, sit near someone else and give this lady a chance?

Sometimes first impressions aren’t always right.

Worry about it all when you’ve got to see a little bit more of her, but don’t leave a coffee morning with people you enjoy and don’t even begin to suggest “getting rid of her”

Good luck
