While we all have our favorite times of year to visit Walt Disney World, I don't think any of us would argue that Disney has been doing its best to change the crowd traffic and influence when people are visiting the most. Actually, I would argue that they are doing their best to spread the crowd traffic out in a manner that minimizes crowd fluctuations and provides a more consistent guest experience across the board.
That sounds pretty fantastic if you were used to traveling at the busier times of year, but if you were a low crowd level traveler, you've got a whole new calendar to memorize to make the most of your Disney trips. Tom Bricker has put together a fantastic look at what the new crowd levels are these days and what his opinions are of the best and worst times to travel to Walt Disney World. While his opinions may not be the same as yours, it's a great article that is well worth the read.
