My upcoming trip will be the fourth time I have used TGM. Although I find the site a little frustrating to use (for example, I have an awful time getting to the forums, and I stumble on an article and then can never find it again...) I find it worth the price just for the "best days" article. When I have used it, it's been dead on. When I have gone against his advice for whatever reason, I have experienced crowds and lines. I LOVE walking on to rides (who doesn't?). I do think that I could research several boards and come up with the info on my own, but for 17 bucks why should I? My time is worth way more than that. One thing that I do find inconvenient, though, is that the best days info has not been available at the 180 day mark for important dining reservations. Overall, for me, definitely worth it.
