So... we're back! We made the trip from CT to WDW and back and lived to tell about it

And I am definitely a convert. We will be driving from now on! It was so nice to be able to bring all of the things we wanted to & not worry about how much the bags would weigh, or missing our flights, etc. (Or that one of the kids would be too loud & disturb people around us.. oh, I could go on and on!)
We were completely on our own schedule & that was a beautiful thing!
We left Hartford at 3 a.m. on Sat 5/21 and arrived in Kingsland, GA around 8:00 p.m. that evening, where we spent the night. We stayed at the Microtel with a coupon we found near one of the rest stops. With tax it was $52 and it was a nice, clean hotel. A great place to rest for the night. We enjoyed the pool before heading to bed.
The next morning we continued on our way and drove another 4.5 hrs (including a gas stop, a stop at the Florida welcome center, and a drive-through place for lunch). So we arrived early afternoon. We were very lucky in that we didn't hit any traffic at all.
Coming home, we left Fort Wilderness at 11:15 a.m. on Sunday 5/23 (we had stayed at MK late the night before so we got a bit of a late start) and arrived in Fredericksburg, VA at 1:45 a.m. We had already booked/pre-paid a Homewood Suites room there, otherwise I would have stopped sooner. I was nervous about availability with it being Memorial Day weekend.
The next morning (Monday, Memorial Day), what should have taken 8 hours to get from Fredericksburg to Hartford took 12. Traffic was really heavy that day and completely stopped in some parts. We saw at least four accidents along the way.
Other than the traffic on the way home (and really, that could have been avoided if we had just driven on another day- we knew what we were getting into!), we had a great time driving.
DH and I enjoyed talking and the spontaneous nature of it all. The kids had a blast, too, and loved having their own pillows, blankets, etc. along for the ride. It was a great family trip. Thanks to all of you for the great advice! It really helped in the planning and made it a much 'smoother ride'
