If you are planning to eat at some of the restaurants on Disney and your family really wants to dine there during your vacation then you'll need to make those reservations ASAP. Many restaurants reserve up to 90 days in advance so if you wait until you actually arrive, then especially during the busy season, you may not be able to get a table at all or get very late table times (like 9 p.m.). We reserve at almost all of our favorite restaurants well in advance. When we tried to get a few last-minute reservations we had to settle for either 4 p.m. or 9 p.m. Its hard to believe but the more popular restaurants really do get completely booked up 60 to 90 days in advance.
