Another big thumbs up to Tour Guide Mike! I'm a huge skeptic too, but the first time we used his advice we were hooked. We couldn't believe that we were spending so little times in lines, even during the high season. It just made the trip SOOOO much more enjoyable.
While the site contains a huge amount of information, I think his goal is to have you understand the WHY of what he's recommending, which I love. That way if you do decide to deviate, you'll know the impact of what you're doing and be able to come up with a new strategy on the fly.
We've used him twice now and are using him again this summer. We wouldn't do Disney World without him!
The good thing about him is that he's in the parks every single day giving
tours, so you get constant updates about crowds, changes, etc.
If you're reading this thread and considering using him, if you go to his Automated Vacation Planner (AVP) Preview Tour at
http://tourguidemike.com/tour/index.asp, you can type "HE7KD-8GA" in the
Promotional Code section of the purchase page. You'll save $3 off the normal
purchase price of $21.95!
