Got a call back. She made it sound like it was only the 14th that was being dropped (due to logistics as she put it) and offered to give us the 16th AND a refund. I thought that was very generous but as the OP said we also have
MNSSHP that night so I declined. Instead she is giving us 3 additional FPs for the 14th. This is our first Disney trip so I guess I don't really know what I'm missing anyway

just thought I would share.
