We did the 9:30 tour in Feb. We had to check in at Guest Services by 9:15.
You'll sign away your right to sue over an injury and then the entire group will be escorted to the training area. Send your wife to sign in while you run for fastpasses for Soarin.
The classroom session took about 45 minutes, then we had a bathroom break before heading out to WS - because we were on the 9:30 tour there were more people milling about - you'll get a kick out of all the bored dads that light up when they see the Segways and want to jump right on!
We found them VERY easy to ride. We are rather small (5'3", 5'7") and it did seem that the larger (read: tall) people in our group (ok - someone yell at me that it is the same for all

)seemed to have more trouble getting the hang of it but did before leaving.
It will only let you go 5mph and "pulls back" on you when you hit that speed, it is a little disconcerting the first time - simply be prepared.
They only point out a few things in WS but it is worth it for being there alone. Our tour had people entering WS for the 11AM opening and because of this, the store were all opening up so it all looked normal. Don't forget your camera, the CMs will take pictures of you.
At the end, we were given a pin that you can only get by doing the tour.
