We have a concern driving southbound using I -75 through Atlanta as we head to Orlando from Toronto. With a one night stopover in Sweetwater Tennessee. To get a pick of the rooms for our 5 day stay, we wish to arrive in Orlando around 3 pm. As young seniors that always works for us stress free. We are travelling on May 7 & 8.
The math... 9 hour drive Sweetwater to Orlando. Under ordinary conditions to arrive at 3 pm we must leave Sweetwater at 7 am, to arrive at the North end of Atlanta (junction Hwy 285 called "The Perimeter") at 9:30 am. We wish to stay on I-75 south through the downtown connector. Unless an alternate route is guaranteed to be achieve our two concerns below.
(1) Loss of travel time resulting in arriving past 3 pm in Orlando
(2) Avoiding stress caused by extreme stop and go, for us and our 2002 Buick Regal.
Can an experienced driver down this route kindly provide us the advice as to whether arriving at 10:00 am instead of 9:30 am at "The Perimeter) would be better for the two reasons above and meeting our objective of arriving around 3 pm in Orlando.
Thank you kindly for your first hand experienced advice and any tips. We do not have a mobile phone or access to the internet while driving, but we have a GPS without traffic info.
