I was at WDW the last week of January 2 years ago & the first week of February last year. Both weeks were busy & several posters report it every time the subject comes up. I have posted our experience at the POR food court many times.... anytime we went for breakfast the food court was packed with families walking around with full trays looking for a table. This was midweek at several different times of the morning. The resort was packed & busier than I had seen in previous August trips.
Wait times were high & the parks seemed crowded. And other posters reported the same things. But our reports were brushed off as inaccurate with the excuse that Disney had played with staffing levels causing false high wait times. But the truth is we weren’t wrong. This time of year is now busy too. And yes, resorts being fully booked does mean parks will be crowded no matter how many times some posters say it doesn’t.
