How accurate is Google Maps for driving times between destinations? Is there another site (Mapquest?) which is more accurate/realistic? I'm talking about longer distance stuff - WDW to near Jacksonville NC (10 & 1/2 hours is what's quoted, which is fine for us) - and a short trip from WDW to Kennedy Space Centre? Just wanted to know if I need to add time for refuelling (both for the car and us), rest stops etc. Thankx in advance for your help!
