Our June trip will be our first to WDW and using TGM. I agree--with the money we are spending for a family of 6 to stay at BCV, what is another $20?
One complaint I have read and even had myself, at first, was that there was not a "magic" touring plan that I could just use. You must be aware that you will have to do a lot of the work/research yourself. There is a lot to read, but once you understand that he is teaching you how to tour, you will be able to figure a lot for yourself.
The forums are great and the people are very nice. I posted my itinerary and made adjustments based on what others had to say, but keep in mind that each family is different. I am an ultra-organized person and love that I have my touring plans ready to go, with a lot of help and advice from the forums.
Good luck to anyone who signs up--money well spent!
