Syracuse is an easy 2&1/2 hr drive (tops) from Kingston. I mean EASY!! We arrived home on Jetblue on a Fri at 4:00pm. While we were on the plane they announced it's now 3:57pm the temperature outside is blah blah blah. We collected our luggage, paid for our parking (cheap, $8 a day), got gas, crossed the border, and walked in our door in Kingston at 6:30pm. AWESOME!! Soooo much easier than driving through Toronto.
The Segway tour was fun and they have a hour training session first inside. Don't worry you will do fine. They say you need good balance which I have and my DH doesn't, yet he seemed to be more comfortable on it than me. It has nothing to do with your driving skills, more like your walking skills!! LOL! I'm sure you'd do fine.
