Well, I wasn't a fan of TGM, but I wasn't so completely dissatisfied as to ask for my money back either. It just wasn't a fit for our touring group. My big complaint is that the information for entry to the parks other than right at rope drop was severely lacking. I thought his updates regarding
MNSSHP were slower in coming than promised, and I found his organizational and conversational styles annoying.
However - we were traveling with two toddlers. They normally slept a good bit later than was required to get to MK XX minutes before rope drop while using Disney Transportation. Tired, cranky toddlers do *not* a happy vacation make. Especially since a lot of TGM's advice made them more stressed because of more crowds or waiting around than we would have otherwise been involved in. They ended up not eating well, not sleeping well and we just trashed the TGM info and did it the way that made sense to us. I think we may have kept the day/color info, since I didn't bring alternatives to that with me.
I've actually heard his FP advice (and a really cool FP/babyswap scheme) from a Disney employee and some non-TGM subscribers, so I'm not sure that I would cuont it as original.
As a guide-book equivilent, it was fine. I didn't find it to be particularly outstanding beyond that.
As a point of reference, we never waited in line more than 5 minutes anyway, and without TGM had some really fascinating encounters that we would have missed if we worried about grains of sand.
