I subscribe to that site have for 2 years, last 3 visits found the parks extremly crowded when there calander says otherwise. Also there line waits way off. I actually don't know if they guess or how accurate there predictions are. The one thing I do know is when I arrive and the park is jammed and they state its a 5 or 6 I have to think they are 100 percent guessing. I honestly don't go by them anymore as they have been consistently way off last 3 visits.Hi there, heading down on Thursday for a week. I noticed the crowd calendar has Wednesday 12/15 as a 6 for that day. Anyone have any insight onto why it would shoot up mid week after being at a 1 on Tuesday and Thursday?
It's part of the upward trend as we get closer to Christmas. Take a look at the following Friday through end-of-year, for example.

Sorry to hear that. I find the site and books very informative. I'll be sure to test out the 1 crowd level prediction a few times when I'm there.
There information and books are great, we just question the calender due to our experiences.
Ill be there next week, hoping its accurate, have it on my Droid so Ill be able to see and definitely keep a record this time as we use to always rely on it, always going when its 5 or under but latly........ unfortunately have been disappointed. I would love to know if they actually have access to ticket sales, booking or if its just guesses based on trends. Last March we arrived only to have the calender go from 7, 8s to 10s as we were there. We were prepared to deal with 7s and 8s but 10s were misery. This is why we tend to think its based on a lot of guesswork so I guess we should take it with a grain of salt and not really base our trips soley on that. We shall test next weeks accuracy and see. Just hope the weather is accurate and the expected warm up is right on!
Predicted vs. Actual Crowd Levels / Park Recommendations
Since June 2010, we've been recording not only our predictions, but how they actually fared based on Lines.
Predicted vs. Actual Crowd Levels Property/Park Predicted Actual Difference
Walt Disney World Resort 5 5 0
Magic Kingdom 3.0 3.1 +0.1
Epcot 2.6 3.3 +0.7
Disney's Hollywood Studios 6.6 7.7 +1.1
Animal Kingdom 1.8 1.0 -0.8
A negative difference means we overestimated; a positive difference means we underestimated.

To figure out the "actual" best and worst parks, we re-calculate using the Park Recommendations formula using data from today.
I'm not sure if everyone knows this, but when we collect data in the parks every day, we go back and calculate what the actual crowd levels were. Then we post the actual crowd levels along with our predictions on the website for everyone to see. An example is below from 29 November, the most recent actual vs predicted day available. (It's messy because of cut-and-paste; let me know if it's unreadable.)
We also calculate our overall accuracy since we introduced the new crowd calendar in early June, 2010, as well as how accurate are our "best" and "avoid" park recommendations.
Since June, 2010, our crowd estimates for all of WDW are within 1.1 points of our predictions, with a slight bias (0.2 points) towards underestimating crowds. For the MK it's +/- 1.0 with a 0.2 point bias towards overestimating; Epcot and the Studios is +/- 1.6 with a 0.4 overestimate bias (Epcot) and 0.6 underestimate (Studios). The AK estimates are within 1.1 with a 0.1 point overestimate bias.
All of those actual numbers are, on average, close enough to the predictions that you'd be hard pressed to tell the difference; I don't think the average person on vacation would notice anything most of the time.
In addition, we're the only crowd calendar which makes available our actual performance against our predictions. You might want to ask why others with crowd calendars don't do this. (Of course, we compare other crowd calendars' predictions to actual park conditions. None are as accurate as ours.)
To be sure, there are days when we're way off on an individual park. Last Friday at the Magic Kingdom, for example, we predicted a 1.6 crowd and it was more like a 7. (We're looking at why.)
As far as we can tell, then, to say that the predictions have been consistently wrong is simply not true. Of course, we're open to feedback. RonAnnArbor, you claim the calendar hasn't been accurate since June. Can you provide your data and methodology for how you determined that? That's a pretty big claim, and it contradicts the tens of thousands of pieces of data we've collected. Since we've made our data and methodology publicly available, I'd love to see how you collected your data and compare your research to ours.
Thanks!
