I just got off the phone with the Disney Reservations line, and I have to say that the CM's I spoke with were absolutely wonderful!! My daughter decided at the last minute to take her son with us on our trip. The original plan was for him to have 2 weeks of "daddy time" while we were on vacation. I'm within my 45 days (14 to go!), and I didn't know if there was going to be any charge for the changes. There wasn't! I also was worried about my ADR's, and those didn't have to be cancelled and rebooked either! I'm so thankful for the great CM's I spoke with today. They made my instant anxiety attack go away with a few kind words and awesome help.
