I am always amazed by the people that think they are going to get a great travel deal on black Friday. Again, most companies start their sales early in the month. Second, if you wait until Black Friday, you probably won't get the best air. You may have to fly really early in the morning or have a connection that you wouldn't have had if you had booked earlier for the same price. Also, systems get so overloaded that properties will be overbooked. When you get to your destination, you'll find out, oops, we don't have any rooms. We can send you to another resort, but it isn't your first choice.
I would recommend, don't plan on getting a good travel deal on Black Friday. It is much better to plan ahead and get the hotel and airfare you truly love.
