I have heard that there have been problems with the reservations system, and some dining/special event reservations (fireworks cruises, Bibbidibobbidi Boutique, etc.) have been, um, lost or locations have been overbooked. So, if you made reservations on your own, I'd advise checking them. If your TA made the reservations, they should be able to check for you (a benefit of working with a TA, no?)
