I echo what other posters have said so far, but wanted to add another thing to consider. You will be going to WDW during one of the busiest times of the year, the week leading up to Easter. I avoid holiday periods at WDW like the plague, however if I did decide to venture to WDW during a holiday period I would not consider staying offsite. Using every strategy available to you during these peak periods is imperative, and having access to EMH is one of those strategies. Also, you likely may want to take a break in the middle of the day, and hopping on Disney's efficient transportation to quickly head back to your resort can be a lifesaver and a timesaver. Is this your first trip to WDW? If not, you likely know what you are getting into, and maybe staying offsite would work for you and your family. If this is your first trip, there is a recent thread on the "trip reports" board about someone who this past Xmas went to WDW for the first time ever, stayed offsite and it was not a "magical" experience for her family. I would encourage any first timer, going to WDW over a major holiday, to find and read that thread.
