Driving from Mississauga to WDW - any tips?

[archdandy]

We've gone that route once. Never again.
Now, granted, we're coming from Kitchener. But we found both Google and Bing were waaaaaay off in their time estimates. First day, left 3:00 am, probably averaged 75mph to the border, the border took all of 45 seconds to cross.
So far so good.
We got to Charlotte at 6:00pm on the dot with minimal stops. That's fifteen hours of pretty much straight driving. The next day we left at 6:30am and pulled into OKW at 4:10pm. Now, granted, there was a hell of a backup in Orlando less than fifteen minutes from WDW...probably cost us 45 minutes--but still. It was supposed to take about twenty hours of driving and it took 25+. Brutal.
Without something like ALONG I-75 to eat the miles, the miles ate us. We took I-75 home: 21 hours of driving--LESS time than Google suggested it would take. That book is a godsend.
77/79 is considerably more scenic, I'll give it that.

Thanks for your opinion! We chose the i75 over the 77/79 because so many people said they prefer it. We've had family who have done both routes and also said they prefer i75. We are planning on bringing along the book too so that's nice the hear that it helps pass the time. Plus like I said earlier, I'm a frequent bathroom visitor so it will be nice to have so many places to stop on the highway.
