If you want a deluxe, your best bet will be Swan or Dolphin. Not technically a Disney hotel, but still a great place to stay. If you are nurse, teacher or any government employee, including retired, you can stay for $129.00/night. That's about half off. Entertainment rate is comparable.
You are obviously aware that Easter is one of their busiest weeks and is considered a Holiday week. Having said that, we stayed at the AKL Easter 2002 for $169.00/night, Savannah view. Our bell man said that virtually every room in Orlando was booked for the week. So even in a slow year, rooms are in high demand for that week. Good luck!
