We just entered our window and booked everything,including the WOC dessert party. I was surprised to be able to do so this early as others have eluded. I like to book the things I know we want now and make changes as the trip approaches. The more relaxed planning at DLR is nice, but still requires attention in the summer as things do book up a bit more quickly for the higher priority locations mentioned by others. Relax and enjoy your trip knowing you don't need FP+ decisions at 60 days.
