Yes yes! Come to Savannah....spend Money!
There are a pile of hotels on I-95 at the Pooler Parkway/Airport exit. There are also movie theaters (IMAX even) and some great food out that way. THere is also a large number of restaurants and hotels at I-95 and Ga 204 about 10 mile south from there.
After Savannah, its about a 5 hour drive to WDW. I just drove down for a solo trip last month and it was great. I left the house at 4:00 am, got through Jacksonville about 7 and it was smooooth sailing beyond that.
The trip back took longer. I left I-95 at Daytona and drove up A1A to St. Augustine. Added about 1 1/2 hours of time, but, was a beautiful drive.
