I don't remember what time we left. The earliest suggested airfare is 11:30 according to passporters. Disney booked us an 11:20 and we had plenty of time. We checked at the port so we only had to go to the gate. I think we still had 1 1/2 or 2 hours. The absolutely latest you will be off is 9, I think. So I would say anytime after 11:30 would be safe, but I have heard people making 11 am flights with no problem, I know we could have. We were not one of the first ones off, had early breakfast, made everyone do potty stops and so forth and then we left.
