In our experience the keywords in the URL do play (but pales in comparison to other on page signals). If you have multiple iterations of these sites, why not do some A/B testings to see what woks best.
Acknowledging what the previous posters are saying but if you are going to leverage this, do a little key word research and find out what the predicted searches look like. We do find that order can make a difference, i.e. Lake Tahoe Boat Rental vs Boat Rental Lake Tahoe. Maybe play with the inverted order of the title tags as a contrast.
Again, other signals are much more important but all things being equal we have seen positive movements with keywords in the URL.
