Me2Me, we went to Universal Studios this time, so ME wasn't an issue for us. However, I am looking at taking my son to WDW during March break and flying out of kitchener again. We will be using ME then.
When we flew into Detroit from kitchener, we first had to clear customs, then we picked up our luggage. Not too far from there, we dropped our luggage off again, went thru security (x-ray again) then off to our gate to catch our connection. It was really easy.
I priced out different airlines leaving from Toronto and Kitchener for our march break trip. Leaving from Kitchener was about $600 cheaper. Add the convienence of flying from Kitchener, it's a hands-down winner for me!
Have a great time on your holiday!
