Two things I have noticed is that TP is underestimating crowd size on a regular basis. .
Agreed. It used to be years ago TP would underestimate, but in the week or two before our trip started they would crank their rating up, thus getting it "right" (which of course is worthless at that point, flights are booked, reservations made, etc.) But this year when I first looked at TP calendar for March 20-28, they had all the days as 6s, and one AK day a 5. Uh uh. Not gonna happen over a prime spring break week. And sure enough, every day they were posting that the levels in fact had been 9s, and one day even a 10. Easywdw at least accurately predicted the week as 9s.
