I hate to hear this! I understand that as humans, sometimes things come up that we can't get out of, but I always get suspicious and wonder if something shady or cut-throat is going on behind the scenes when everyone I'm scheduled to see suddenly has a crisis. I certainly don't like making visits to other places and relying on last minute bookings because ample time is required for the screening process.
I hope these AR guys are able to straighten up to show your beautiful self a good time so you won't have to cancel your trip!
