I couldn't edit the post at the time, should have read 'should' be ok for our holiday
Not actually sure we 'will' be able to get there but we're crossing everything possible.
What they said was, 80% chance this op will fix it, if not second op, in which case no chance of holiday
And 6 weeks might be pushing it for the gas ball tbh, but am hoping they might know a bit more after they've done it tomorrow.
I so wish it was something like a broken leg where it's down to the person wanting to do something, but in this case it's not a choice
