The slide show doesn't shows up correctly here, visit the site and there you can view the sideshow and get more information as well.
The Areca Islands is built on a large size map. There are a large number of lots (90 total) and plants – warning for those with slow computers. This neighborhood requires The Sims 3 World Adventures Expansion pack to play.
In addition, you must have the rabbit hole replacement rugs from Custom Sims 3 in your game before installing The Areca Islands. Without these none of the community lots that Sims disappear into will work. Without them, none of the following lots will be available: book store, grocery, diner, spa, school, theater, city hall, office building, stadium, science facility, military base, warehouse, police station, hospital and mausoleum.
The Areca Islands includes all base game spawners for beetles, butterflies, gems, rocks, meteors and fish, as well as many neighborhood effects and lots of decoration.
IMPORTANT

Visit Sims3Town for more information on neighborhoods and lot information.
Well the slide show didn't work here, but if you visit the site, as I have mentioned and linked you will see more of this glorious island and get all the information and details necessary for this island to work properly and correctly. :-)
