I booked to attend a conference, paying a non-refundable deposit. A week later it was announced that the conference venue had changed. It will now be held somewhere which is not accessible by public transport and is a further 45 minutes drive away (when I do not have access to a car).
Presumably this does not make a difference to most delegates but it poses a huge headache for me and makes it no longer worth attending. If they had said it would be held at this new venue in the first place, I never would have signed-up.
I contacted the organizers to explain my situation and ask whether, under the circumstances, I could possibly have my deposit back. I was told definitely not and that I will just have to hire a car to get there (at my own expense, obviously). Does that sound reasonable to you?
