Walt Disney World restaurants can be booked 60 days before your trip at 6am Eastern Time through the mydisneyexperience account.

You will not need a Lightning Lane for 7 Dwarfs Mine Train if you arrive during the morning extra magic hour in the Magic Kingdom and go directly to 7 Dwarfs Mine Train. The wait time will be only about 15 to 20 minutes in the standby line.

If you want to get a Lightning Lane for Slinky Dog Dash, make sure to plan to go to Disney's Hollywood Studios during the end of your trip. 

There will be an hour time window to select for a certain attraction to go in the Lightning Lane. You can modify this time or the selection after it has been reserved. If you are modifying it, keep refreshing the screen and new times will continue to appear. You might get lucky and get the better time you want! This is especially true early in the morning.

There is a shortcut from Main Street to Tomorrowland and back to Main Street that goes through the Tomorrowland Terrace Restaurant. You can avoid huge crowds this way in the Magic Kingdom.

When you get in the Haunted Mansion, you will first enter one room and then another. While in the second room, stand under the woman holding an umbrella. The door behind you will open, and you will get ahead of the crowd to go on the ride.

Tower of Terror will be a walk on if you arrive during the early magic hours.

There is a single rider line at Rise of the Resistance. It will be a much shorter wait; however, your family will be split up.

You can get water for free! Walk up to any quick service location and ask them for water with ice. They will give you cups of water for free.

You can either enter the Seas with Nemo & Friends by going on the Nemo ride or going through the Nemo exit, which is on the left.  Inside is the 6th largest aquarium in the world and the 2nd largest in the United States.

Child Swap or Rider Switch is a very valuable feature Disney offers for parties who have a child who is not tall enough to go on a certain attraction.  Go to the entrance of the attraction with your child and ask for a child swap pass.  Then, everyone goes on the ride except for the person who is staying with the child.  The riders go through the entrance of the attraction.  When they return, the person who was waiting switches with the people who went on the ride.  The person that did not go on the ride takes the rider switch pass and can take up to 3 other people with them.  The service is Free!
