Already a leader in the vacation rental e-niche, Zonder just added a slew of helpful features, like exact nightly rates and exclusive last-minute deals (garnered through their network of professional property managers) directly within search results, the ability to plot results on a map, and an enhanced search with easily filterable info, including price, pool/hot tub, beach proximity, or internet access, which you'll need to book another rental when you realize you've also got sweet nude-fat-people-beach proximity.
