>Ok, I called. The owner of the place is in another state, but I'm going to meet with the manager (Sue) at 2:30. Not exactly sure, what should I ask from her after stating my case... I would like the full refund, of course...

Ok, good, wait for his/her reaction first. Let me them absord the situation and see what they have to say. Then, you may react on that. You may prepare some demands, etc. I think, based on this situation, that this is a fair thing to do.
