My mom and I are going together in November. I know its gonna be an awesome trip. Shes the one who actually turned me into such a disney freak that I am today. She hasn't been there since 2006 so I'm real excited for her. We go every year in november, the week before thanksgiving week and boy is it beautiful at that time of year...and the crowds, well there are none really! We are staying at POFQ for the first time so thats always fun, staying at a resort you've never been to yet. I stayed at POR lastyear and so far its my favorite wdw resort! I chose FQ because its not as big, has the boat transportation to DTD, and I have heard nothing but great things about it. If you go for a value resort, you should try Pop Century. We love that Pop, its nice and spread out (not spread out like the mods, but a little more spread out than the All Star's), Pop has a great foodcourt, and doesn't share busses.
I have never been to wdw during easter week, but have heard from many that it is veryyy crowded. Just pace yourselves with everything. Don't rush, and just make the most of everything. You'll have fun no matter what.
