Has anyone ever figured out what their average speed is when driving to WDW? I usually go 3-4 MPH over the limit, but that doesn't take into account traffic, lower speed limits going through big cities, weather, etc. All of the online mapping programs seem to use different average MPHs which gives us estimated drive times from 17.5 to 20 hours. I'd be curious to see what some of the veterans here average. Thanks.
