I see you are coming to DLR in May. Be advised that the Diamond Celebration begins on May 22. If you are going to be here during, or after that time, you may want to book dining packages as close to the 60-day mark as you can, just to be safe. Especially for WoC, since the show is changing. If you are coming before the anniversary celebration begins, you will be fine booking ADR's up to 2 weeks out. Of course there's nothing wrong with booking as far out as you can. It's just not that necessary at
Disneyland.
