I use a couple of tools to determine good keywords to go after. What they do not tell me is the amount of traffic for the long tail words.
For example, I know people search Hualalai vacation rentals, but I can not find the amount of traffic for that. Does anyone have any good ideas?

Rob, have you tried Google's AdWords keyword tool? By traffic are you meaning the number of times that phrase is searched?
