I usually rent from owners in Palm beach shores, now it’s only redweek rentals. This site is more like a Vrbo. Trying to find something in Feb.
With Redweek you generally have to rely on what people list. Their FAQ suggests getting notified when new weeks are posted.
If you want to customize and have an owner book what you're asking for you can check out Book My Points (.com).
