There's another thread on these boards about TGM but I don't remember where it's posted. Yes it can save you money and time. I highly recommend TGM. It has some great insider tips that you may not find anywhere else, lots of articles and photo tours, reminders for making priority seatings, touring recommendations, dining guide, theme park and attraction descriptions and much more. I purchased it several months ago to help in planning our first trip 8/04 and I already have a basic itinerary put together.
