You maybe might get high xx for it on DL, but I think it's really only good for development. Problem is, you've only got to search for the phrase in google to see what you are up against! Google business listings and ads dominate the entire "above the fold" area of the first page, then the first organic results is TripAdvisor which I imagine get's the vast majority of the clicks. At least if you developed it with a good directory site, it would increase it's value for that alone.
