The dates provided are according to Disney's dates. Disney has 5 levels of crowds. Level 5 is the worst and most busy time to visit. If you went to Walt Disney World during one of the times that is recommended, you would see a large crowd and think I'm nuts for recommending that time. There's a big difference between what we consider to be crowded versus "Disney Crowded".  There are no slow times at Disney anymore. There are "less busy times". Dates will change year to year depending on when some holidays fall. If at all possible, these are the worst times to avoid in 2019 and 2020, which are considered to be level 5 out of 5 levels:


  • April 14 - 27, 2019
  • December 24 - 31, 2019
  • April 5 - 18, 2020
  • December 24 - 31, 2020


Other really busy times that are not recommended, in addition to the above dates, and are considered Level 4 out of 5 levels:


  • February 16 - Apr 13, 2019 (Spring/Easter Break)
  • April 28 - 30, 2019 (Spring/Easter Break)
  • June 11 - August 15, 2019
  • November 27 - 29, 2019 (Thanksgiving)
  • February 16 - April 4, 2020 (Spring/Easter Break)
  • April 19 - 30, 2020 (Spring/Easter Break)
  • June 11 - August 15, 2020
  • November 25 - 27, 2020 (Thanksgiving)


The remaining weeks are listed below. Level 3 of 5 is still very crowded, but not nearly as bad as levels 4 or 5. Level 2 of 5 is almost empty according to Disney, but still very crowded to us. Level 1 of 5 is prime time to go to Walt Disney World. Please remember that our version of slow is very different from "Disney slow".  But, trust me, all of the weeks below are WAAAAYYYY better than any of the weeks on levels 4 and 5. 


Another very important thing to remember is that the weekends are never really that good year-round (especially holiday weekends).  **Some weeks listed below include holidays, which will be busier than the slowest times, but, certainly, not the crazy, busy times like Christmas, summer and Spring/Easter breaks. The weekdays are always best in the weeks below.  


With all of that being said, here are the weeks that are considered to be "slow" according to Disney (levels 1, 2 and 3):


2019

                                    15 - 23 (Level 2 of 5)


It's also important to remember that there are 52 weeks in the year. It all depends on what days fall where and when full weeks begin, which also determines when kids go back to school or get out of school. This list is based on Disney's 2019 and 2020 dates.


Final thoughts, tips and personal experiences: Be mindful of holiday weekends like Memorial Day, Martin Luther King Jr, Labor Day, etc. They can be more crowded than usual, but not too busy to change your vacation. You may just want to avoid the Magic Kingdom on the weekend and go on a Tuesday, Wednesday or Thursday. And, avoid Epcot Friday-Monday during Food & Wine Festival. In my opinion, the first week in January is pretty busy, too, because of people who are still there from Christmas week and marathon weekend. There's a significant drop in crowds from the holidays, but the rooms are packed with runners from all over the world and there is a boat load of traffic.
