We are going nov. 11-18th. I wanted to extend the departure day to the 19th. The CM said there was no availablilty for my reservation at the fort cabins. However I can bring up fort wilderness cabins and book the 11-19th online. Is it because of my discount?? They are giving me 15% off. As it looks like the 19th and 20th are not included in the discount. And it was about $788 more, just to add one day and tickets. Which is crazy. Any thoughts? Oh its a saturday too.
