Like others have said, it really depends on what you want out of the resort. We have two, sometimes three, days that we spend a good bit of time at the resort and taking advantage of the resort amenities.
Another big "plus" at the moderates are the bigger rooms and the covered bus stops. The bus stops at the values are one line for each park and they are not covered. I know that it may sound silly to some but I do not want to stand in a line to catch a bus in the mornings. I do enough line standing in the parks.
