Another vote for Tour Guide Mike. This is my second vacation planning using his guide and I just can't say any thing but nice things about it. Having been numerous times I still find it a very valuable tool and he constantly updates it with new information. Also, he just recently started a chat board which is only for his members and you can get a lot of hints on not only how to use his plans but other good suggestions from his users.
Also, there is information contained on his site that I have not seen anywhere else so again it certainly is worth the small fee he charges.
