TGM is AWESOME! You can't go wrong. Be sure to follow his advice on how to use his website once you subscribe as many, MANY, MANY folks find it quite confusing and give up too soon. But if you do get in a situation where you can't remember how to find something, just click over to the forums and someone will be there to help you find it. I just used TGM during our Nov/Dec visit. It was our first. I planned based exclusively on TGM and he never steered me wrong. I bought the UG and PassPorter and read them from cover to cover early on in my planning. However, once I got down to planning which parks I would be in on which days and booking ADR's, I used only TGM's advice. The books are great when you want a Disney "fix" but by the time they're printed and distributed to your local bookstore, some of the information is already out of date. TGM keeps his information current at all times via his website....which is why he doesn't publish his own book. See? Makes sense doesn't it? If you do decide after you subscribe that it's not for you then, request a refund. He'll give it to you, no questions asked. Good Luck! (Oh, and if you renew....it's even cheaper!)
