BaileyBelle,
We live in NH in the Dartmouth Lake Sunapee area. We just got back from Disney Saturday night.
First of all we have a Class A motorhome and drive approx. 57 MPH so if you have a car you can drive faster.
We too wanted to avoid traffic in the cities. We drove I91, I84, I81, I66, RT 17 to I95.
We left Enfield, NH @11:45am on Friday 4/1. We stopped for approx. 1 hour in NY for dinner and at a
Walmart in Hagerstown, MD. to sleep from 11:30 pm to 2am.
We drove until approx. 8am stopping at a Cracker Barrel for breakfast. (approx. 1 hour stop). We stopped again in the mid afternoon because of the winds whipping the motorhome around. We took a nap and had a late lunch (approx. 2 hour stop). We arrived at Disney at 12 midnight Saturday 4/2. We also stopped for gas 4-5 times.
We didn't hit any traffic in Richmond because it was too early in the morning. The other city we hit (missed the 295 bypass) was in Jacksonville. It was 9pm and the traffic wasn't bad at all. No traffic on I4 through Orlando to speak of -- as it was 11-12 pm.
We figure the driving rain/winds that started in southern Virginia all the way through South Carolina delayed us 2-3 hours. We also hit winds through South and North Carolina coming back.
The trip back we left Disney at 4am Friday 4/15. Took 295 bypass through Jacksonville around 7:15am (low traffic). We stopped for dinner and gas only and arrived at the same Walmart in Hagerstown, MD around 12 midnight. The next morning we were on the road again around 8am and arrived home at 7pm. We made more stops (15-20 min) during the later part of this drive as our 3 year old had enough. We stopped about every 2 hours so she could run around at the rest areas.
Total time 36 hours down and 39 hours back.
We considered the other route you mentioned but when I mapped it out on Good Sam trip planner it was actually more miles. I can't remember how many more.
hope this helps. Probably more info than you wanted!
