I'm going to play here, using TP's observed crowd data to make some suggestions.
For Entertainment Purposes Only, Merely Fun with Numbers
MK:
I think MK very well might break the 20M/year barrier. If they break 7.6% growth They pass it. Its very possible.
If you take out the OffPeak crowds caused by hard ticket events (31), MK's total OffPeak drop from 69(19% of the year) to 38 (12% of the year), it starts showing a small pattern. Those 38 times should be easily off-set by their 52 Peak Days (14.25% of the year). The rest of the time, 244 "Average" or straight up solid days. On those 244 average days? 93 (25.5%) were ranked 4 & 5, suggesting slightly below average & average crowds. 151 times (41.4%) it ranked 6 & 7, or above average. That puts 203 days (55.6%) of the year above as an average crowd.
So its going to be close. Data suggests the growth should be at least 6-7% at MK at the very least. However, I'm feeling especially bullish so I'm going to predict 10% growth at MK, MK is the first Theme Park (in the World) to break 20M guests/year. Champagne is everywhere and this becomes the talk of IPW at the closing party at Universal. MK gets 20.4M.

Epcot:
Epcot had 49 Peak days (13.4%) vs 97 (26.5%) Off. The very off peak days (1&2) are in line with MK, right around 12%. Looking at their average days? 125 (34.25%) below average/average. 94 (25.75%) above average. Makes it 39.2% of the year Epcot had an above average crowd. Call it 5% (as the F&W/F&G numbers dont factor in with my crowd data) and they come close to 12M. Otherwise? 3% and we finish around 11.75M
Studios
Completely flat at DHS. The words to describe the conditions at DHS lack definition, 63% of the year (232 days) they had an average crowd or below, with most of those coming in the first half of the year, before Frozen mania hit. Total of 124 (34%) offpeak. The very off peak (1/2) days were 20.2% (74). Numbers for above average/below average are below Epcot's by about 4%. Studios saw an above average (6+) crowd 36.4% of the year, or 133 times. I'll be generous and say 3% and say they hit 10.4M
DAK
DAK performed a lot better than DHS. 55% Average and below days vs 45% Above average. Only thing negative is their 111 offpeak (30%) days. Call it 5%, DAK hits 10.7M, pulling farther ahead of DHS.
TL;DR? MK 10%, EP 5%, DHS 3% and DAK 5%.
It will be fun to match up the numbers that come out tomorrow with this.
