Ok, firstly, don't worry. Stuff happens. I can tell you from personal experience that things don't always go the way you want them to, especially if you are relying on other people somewhere along the line.

I think for an event like this you need to give yourself lots of time. It's very tough to arrange anything quickly. My personal opinion is that the outcome should be getting the event on in the best possible way you can.

So, if you have to wait, then wait. Make sure you do the backend work first...in other words, get the agreement from the mall office that it can take place, and make sure all your logistics are in order.

Don't panic. Take a breath, learn from what went wrong, regroup and make it happen!!!

And thanks for keeping us in the loop about it.
