TGM is Tour Guide Mike. He has a website and offers updated advice based on what trends he is seeing at the parks (he's a VIP tour guide). We used his advice last September and it was AWESOME! I'm a big fan. As for him being wrong about AK, I'm thinking that the crowds may be due to Expedition Everest opening. They're probably going to be a little thicker there for a while since the ride is new. Overall he has great advice.
