My thoughts on the increased crowds:
-- Improving economy, more people are traveling. Or maybe the same people are traveling more. Or both. My DH and I are getting 4 trips out of our APs. And we live in Buffalo, NY. Even I can't believe how many times we're going this year.
-- Disney is trying hard to eliminate slow times. The
Festival of the Arts at Epcot & Disney After Hours are new in the last 2 -3 years & are offered during the traditionally slow winter months. And yes, they are bringing people in. I planned a 3 night trip just for DAH. There are several other people on that thread that are planning trips just for DAH. I'm sure people are planning trips just because of the Art Festival too.
They have expanded the popular Food & Wine Festival & the Halloween parties right into the slow weeks around Labor Day. There are cheerleading competitions in January, February, April & May. And then we have Pop Warner in early December. If I remember right, the Flower & Garden Festival got extended a few years ago too.
-- Run Disney events in January, February, April & October are all really popular & bring in the crowds.
-- More schools on year round schedules with week or longer breaks in the fall & winter months so people can travel at different times.
-- Disney is letting other online travel sites market & book their rooms. They never did that years ago. You could only book thru Disney. So they are getting exposure to people who wouldn't necessarily go looking for a Disney vacation.
-- Every travel book & fan site has been advising going during the slow seasons for years. With Disney pushing more advanced planning on their website, I think people are doing more research than they used to. So I think more people are trying to plan for the slow season which makes it busier.
-- It has been an awfully cold winter so far, making more people think about taking a vacation.
And I agree poor staffing by Disney & fastpass plus actually make things seem more crowded.
