One thing to be aware of it that the DME may not (won't?) show up on your My Disney Experience reservations. In the past, I thought I was able to both add and view my DME reservations on the website. Now, I'm not able to do either. I called and had my flights added. Just to make sure everything was all set, when I called back about something else, I inquired to make sure they were entered correctly and there were no problems - now just to wait to use them in August!
