I am a personal fan of Tour Guide "Me"
You know, truthfully, I find it more enjoyable to do the research by visiting allears, themouseforless, the Dis and a few other boards, deciding what I want to do and trying it. That way, I am not seeting my expecations too high and flying in for a let down if somebody's else's opinion is not the best.
Having said that, I have never used TGM, but my friend has and says it was not a total waste of money, but she does better on her own from her own experience. That is half the fun.
