I won't link to it because it's hosted on a CC site, but there is Riverblossom Hills, hosted on Mod The Sims. It has a slightly more forested, hilly feel to it than Union Cove, but with all venues from the first four EPs (including WA lots), and plenty of room to expand for later EPs. In my opinion, it's one of the best worlds for TS3, and one of the few that can rival Union Cove. It's CC-free too, if that's the way you play.
