When is the best time to go to Disney World?
Take a look at Historic Disney World Attendance levels, this will give you a place to start. The most crowded times at Disney World are when school is out. If you can avoid those times of the year youll be doing yourself a favor. The theme parks have shorter operating hours during the off seasons but you'll get more accomplished in a shorter time with the smaller crowds. Spring and Fall bring more favorable temperatures to Central Florida, Summer can be very opressive with the heat, humidity, and afternoon rain showers
Also check out the Disney World Calendar of Events to see if there is a special event that really interests you.
Disney periodically closes attractions, restaurants, etc. for refurbishment; check the Rehab Schedule to make sure your must do isnt closed.
Recently I ran across a great site which has a super planning tool called: The Disney World Week Picker App. It helps you select the best time to go to Disney World for your family. Its located on the The Walt Disney World Instruction Manual web site.
By answering a series of questions youre guided to picking the best times to go based on your likes and dislikes.
The Week Picker App is located here.
There is also page listing 2010 Weeks to Visit Walt Disney World, Ranked in Order.
The main focus of this site is for first time visitors to WDW but theres a vast amount of info for everyone. Take some time and look it over!
