Our family of 6 (adults, kids: 12, 9, 6, 20 months) went Easter week 2010 and stayed a 2BR savannah view AK-Kidani, that we had booked 5 months out.
We arrived sat (day before Easter) & basically hung around the resort that 1st day and then went to Downtown Disney. That was a mad house, wall to wall people with over 90 minute waits for any meals - wish I had made a reservation as by the time we were seated all the kids were falling asleep literally on the table as we waited for food (at the Dinosaur restaurant). This night was the worst of the trip - and the one I had least planned for, just assumed we could stroll around DTD.
DON"T GET SCARED - After that night trip was GREAT.
Easter Sunday there were activities to M&G the bunny & other characters right at the resort in the morning & then we went over to Animal Kingdom for am. For Easter dinner we went to MK Cinderella's Castle at 6:55pm - which had been booked at 180 days. Then rode some rides & saw the fireworks.
Monday: Hollywood Studios, 2:00 Sci Fi lunch
Tuesday: Epcot, adult only 8pm dinner at Swan - Blue Zoo
Wednesday: Magic Kingdom, 9:00 am Crystal Palace
Thurs: HS for am magic hours (just the girls), pool, 7pm dinner at Sanaa
Fri: Epcot, 5:40 Chef de France
Sat: 10:40am 1900 Park Fare breakfast, MK for a few hours, 3:00 pickup by Magical Express
Yes the parks were all busy, busy, busy - but we knew that going in & didn't have a "must do this" plan. Used lots of FP, adults split up some: I took the 7 & 9 yr old girls who wanted to rides rides so would get up & go to magic hours to make it happen, while the boys did more relaxing. Baby got lots of sleep & really enjoyed his stroller. Because it is a peak week too, there are lots of extra hours, characters out, shows, etc.
As of this minute, yes we would go back again at Easter (or Christmas which was our other big week at Disney), That said, our next trip is now booked for Nov 5-12, 2011 which is considerably slower so I may have a different opinion after that trip!
Vacation is what you make of it - have a great time!
