You must have at least the EPs,

and the SPs,
if you want to use this pre-decorated neighborhood.

NOTE: You can TRY it without these. It may work but just not show some of the items.
ALL the neighborhood trees are from the EP.

Unfortunately, I've discovered that there's no way to guarantee that every beach lot you download from anywhere will fit on any given vacation lot on any map. All the BLANK lots will fit here (and on the Peninsulas map), but there are some finished lots that simply won't fit much of anywhere. I spent two whole days trying to engineer the perfect beach lot map, but it's virtually impossible, as far as I can tell. If anyone else can come up with one, I'd tip my hat (if I wore hats). :-)

There are ONLY trees decorating the map, and they're all from .

To use these files, unzip the folder, then copy the two files you'll find inside. These particular files are appended with the N124 name, in order to go directly into your N124 (Peninsulas) neighborhood. You may put them in ANY neighborhood, simply by changing the N124 appellation to Nxxx, with xxx being the 3-digit number to match the neighborhood you want to use. For instance, if you want to use the map as a vacation suburb with Pleasantville, rename the files so that they begin with N001 rather than N124. That's it. Keep a copy of the original files somewhere so you may reuse them for other neighborhoods. Go in and play your game, and the suburb will show up as a vacation destination for the neighborhood in which you placed the files. NPCs and Townies will be generated only as necessary.
