When the AP codes first came out this week. I called and booked a room only. Two days later I called back and asked to add the dining. The CM had to cancel my first reservation, refund my credit card, then booked another reservation, gave me a new confirmation number, and recharged my credit card. He also gave me a cancellation number for the first reservation. He said they had to do this because adding the dining plan made the reservation a pkg, which was then subject to the pkg rules (paid in full by 45 days out and penalties for changing, etc). My room only confirmation number was a 12 digit number, whereas my AP room with dining confirmation number is a 8 digit number. He said it was because the 12 digit confirmation numbers are for room only and the 8 digit confirmation numbers are for packages. He also told me that I could make changes up to 45 days out without penalties, but if I made any changes after that that I would have to pay a change fee (unless I did something that would make the price go up, in which case the change fee would be waived, i.e. upgrading from the regular DDP to the DxDDP or upgrading to a more expensive resort).
