Also want to encourage you to keep trying. Even up until that day! We have A&E scheduled for the 14th, but have prepark BOG earlier in our stay. If we can meet them on the BOG day, (which I'd prefer) I'll cancel the 14th. I realize that date doesn't help you, but my point is there's a chance I'll be canceling within a couple of days and I imagine others will change plans like that too!
Good luck!!!!!
