If you have little kids, the moderate might be more appealing to them.
The size of your group may also influence your decision.
If it is just adults, I would pick SOG if the prices were pretty close.
Regarding cost and transportation, the situation is not as nice as it was a few years ago. You now have to pay to park your vehicle to EP, AK, and DHS. This is on top of the 5 dollar a day parking deck fee for each day you are at SOG.
The bus transportation from SOG is not quite as convenient as the Disney resorts. (their bus drops you off at the TTC and then you have to take the monorail to MK ......a Disney bus drops you right off at MK)
At SOG you get a nicely appointed large room with a fridge.
Without discounts offered by Disney, it is SOG hands down......but with the discounts being offered, the choice may not be so clear.
