As for reservations, making them 11 months from date of departure from WDW should be fine. We have had no problem getting Easter time making ressies anywhere from 10 to 11 months out. Both the week leading up to Easter and the week of Easter are two of the three most crowded weeks of the year (Christmas Week is the other); basically, crowd size is 3 to 4 times as large as an off-season crowd, about 70% larger than other spring break weeks and about 50% larger than summer weeks (other than July 4 week which approaches the size of the Easter crowd). MK has very huge crowds during all days in that time and on Easter Sunday it often is close to or at capacity (most go there that day under the impression MK has something special that happens Easter Sunday that does not happen other days of week--it doesn't, thus avoid it on Easter Sunday. To give an example of how bad it can get, it is the only time of year I have ever seen Test Track reach a 3 1/2 hour waiting time for the regular line. Nevertheless, you have long park hours (MK to midnight, MGM to 10:30 or 11) and it can be done by using fastpass and hitting parks at right times-- early in the morning; late afternoon and evening on non-ee days; hitting popular rides during parades or Fantasmic. Normal ee is sometimes dispensed with as they will sometimes just open the parks an hour to an hour and a half early to everyone. There are no e-nights during that time. It is critical that you make dinner reservations in advance as typical response to a walk-up at 6 is that next available seating is at 9:30 or none at all.
