Try back at the Dining phone number in a few weeks if there was one you wanted and didnt get. The final deposits on the free DDP were/are/ will be due by the middle of August, so those who are cancelling trips will hopefully have the courstesy to call dining and cancel their ADR's also (Disney CRO asks you if you have any to cancel when you cancel the room package) A lot of ppl double book dining (2 diff restaurants for the same time--wish Disney would not let you do that but, what can ya do?) till they decide where they want to eat. Hope you get want you want. Dont forget to cancel the original if you do book.
Crowds this year I am not sure on. I havent been for 2 years now(1st year of free DDP) It was dead that year. From what I understand the restaurants tend to be more packed then the parks. LOL
You can find out about attraction closures from the official site. Go to Disney.com and click on parks. Pick any park and scroll down on the left side column (I had a hard time finding the first time) Toward the bottom there is a link about it. Just click on that and it will take you to a separate page where you can pick which park and which month pertains to your trip. Allearsnet.com also is pretty up to date on closures. Sometimes B4 the official site....LOL
Have fun. We will be there the 10-15 at POP. I will wave hi to your cabin/campsite as we go by on the boat. LOL
