I watched the posts this last year at Easter pretty closely as our trip was right after Easter. The posts seemed to say that the crowds were building, but not crazy until the weekend. The weekend was generally unbareable though due to the lines and crowds. 2 hour wait times and main street was shoulder to shoulder. This seemed to be the case the following week also.
The weather was a bit rainy, but when we got the week after Easter week the weather was amazing, the crowds manageable and all the magic we hoped for.
