I think it will be a little busier than normal. Alot of the NY metro area has spring break then, and I even tried to get a few different flights that were booked and then I tried for a few ps, one crystal palace was booked all week for dinner the last week of april, at least for our family size. If you plan well and use fastpass and make any priority seatings for meals you want that will help, also if you will be an onsite guest, take advantage of the early morning and late evening extra magic hours. The weather should be near perfect. We were there last april, easter and most of the time was great, a little rain and one very cool day. But other wise we had shorts on all the time, anything beats all the snow we have been having here. We will be there starting april 24 and I am looking out the window at the snow on the ground, I am definetely disney dreaming. Plan to do alot of swimming and soaking up the sun too. Bring your sunscreen.
