12. Plan!
When it comes to your Disney trip, the best piece of advice is to plan - plan early, plan extensively, do your research and learn all you can about it. You can (and should!) make dining reservations up to 180 days in advance. FastPass reservations should also be made well in advance (usually a 60-day window). Find maps online or request a planning kit from Disney, and study your transportation options, food options, park hours, and special events. Understanding how Disney works will make a huge difference in your vacation!
