Booked the tour 5 days ago for my upcoing trip in Oct. I got my confirmation number over the phone when booking, but do they send email confirmation for the different tours?
Disney does not send email confirmation for tours, and they won't be visible on MDE. Just keep your confirmation number and you'll be fine. That being said, I've taken most tours, including both Segway tours (you'll love this one BTW), and they have never asked me for my confirmation number. Just my name has been enough.
Those Segway tours got me hooked on that vehicle. We took a Segway tour in Washing D.C. last year to see all of the monuments and memorials. This past Sunday we took one at Angel Island in SF. They are so much fun.
