I was a little skeptical about how the guy would know what park to be in on a particular day. I figured if it didn't work, I could always ask for my money back. So I bought a subscription, and we used the "which park on what day" advice. We were amazed how accurate TGM was. Each time we followed his advice, we found short lines and lower crowds. When we decided to go against his advice one day because the kids were dying to go to the MK, we were sorry. Long lines and crowds made us go back to the "plan" with TGM for the remainder of the trip. It is so worth the little amount of money. He gives great advice on resorts, tours, entertainment, best spots for parade watching, fireworks, etc. Just so much advice. I bought a renewal when we returned home for a discount. I am planning our next family trip in March and hope his advice will help with a busy time to avoid the lines.
