Would you pay that much and be there in 1hr 40 min? +2hrs here +2hrs there +parking +car rental+++
No, Pack your car at 6 a.m. leave your drive way, check into your room at 4 p.m., go to a fancy resaurant at 7p.m. and get a good night sleep for WDW the next day.
Then again, we live in Boston and driving down in my Xterra would take 22 hours and cost $450 round trip, we're paying $496 (+$80 transfers+200 car rental) on Song for the 3 of us.
Good Luck
